Support for password authentication was removed on August 13, 2021. Please use a personal access token instead – Fix for Mac

Hey everyone,

If you’re like me and a bit slack with your personal projects you might’ve started receiving the following error today:

admin@Admins-iMac ui % git push
remote: Support for password authentication was removed on August 13, 2021. Please use a personal access token instead.
remote: Please see https://github.blog/2020-12-15-token-authentication-requirements-for-git-operations/ for more information.
fatal: unable to access 'https://github.com/Buzzology/referrer.git/': The requested URL returned error: 403

As the message says, Github wants you to start using a Personal Access Token (PAT) instead of password authentication. Luckily, the fix is pretty straight forward – you’ll need to create a Personal Access Token and then update your keychain.

Step #1: Create a Personal Access Token (PAT)

To create the personal access token, login to Github and go to the following page: https://github.com/settings/tokens

You can also get to this page via the following:

  1. Click on your profile dropdown
  2. Click settings
  3. Click Develop Settings (on the left)
  4. Click Personal access tokens (on the left)

Once you’re on the Personal Access Tokens page you should see something like the following:

Click the Generate new token button, set an expiry and then copy the generated value (you’ll need it in the next step).

Step #2: Updating your keychain

Now that you’ve got your Personal Access Token you need to replace the password that you’ve currently got stored in your keychain. To start, open search and bring up Keychain Access:

If you’ve got quite a few keys there you can filter them by searching for github. You’ll then need to double click on each of the entries and replace the stored password with your personal access token:

Note that you’ll first need to click Show Password.

Now that your keychain is updated, close and then re-open any of your terminals and you should be good to go.

Avoiding “declared but not used” in Golang while testing

Hi everyone,

I come from a mostly JavaScript and .NET background and am currently transitioning to Golang. I’m really liking the language and ecosystem so far but one thing that has irked me a little is that I can’t leave variables as placeholders or even for debugging.

var placeholder1 [][]string
var test1 string

Something as simple as the above results in two compiler errors stating that the variables are declared but not used`.

A bit of Googling showed quite a few people with similar complaints, but there was one solution that seemed to fit my use-case pretty well:

var placeholder1 [][]string
var test1 string

// Use discards
_, _ = placeholder1, test1

By simply using a discard the compilation error can be circumvented. There’s a fairly detailed discussion on Stackoverflow: https://stackoverflow.com/a/62951339/522859

Goland Unable to Resolve Directory – Modules not loading (Mac)

Hi everyone,

I’m trying out Goland on an old Mac and hit a bit of an issue where it was unable to resolve most of my modules. The weird thing was that if I ran the project from a terminal it was fine so this seemed to rule out any path issues.

This ended up being a few IDE settings – double check the following:

  • Click “Goland” in the top left
  • Click “Preferences”
  • Expand “Go” in the sidebar
  • Click “Go Modules”
    • Check “Enable Go modules integration”
  • Click “GO PATH” in the sidebar
    • Ensure that there are zero entries under the “Project GOPATH” and “Module GOPATH” headings
    • Ensure that “Use GOPATH that’s defined in system environment” is checked
    • Ensure that “Index entire GOPATH” is checked
  • Click “Apply” and “OK”

You may need to wait a short while for that indexing to refresh. If it doesn’t look like it’s doing anything run “go mod download” from your terminal. If it’s still broken restarting Goland seems to fix it up sometimes as well.

Unable to parse parameter: azuredeploy.parameters.dev.json – Azure Bicep

Hi everyone,

I’ve been trying out Bicep as a replacement for ARM templates for a mini side project to replace the TFN generator people are currently using on this site. These are a few of the small issues I’ve hit while working with it.

Unable to Parse Parameter

One of the steps on the main tutorial gets you to use a parameters file to make the deployment generic (similar to Terraform). Unfortunately, I started getting the following error:

Unable to parse parameter: azuredeploy.parameters.dev.json

I mistakenly thought that this we referring to the format of the parameter itself. However, in my case it simply meant that it was unable to locate the parameters file. If you’re getting the same error double check the file path and ensure that it’s accessible from the location you’re executing the deployment.

Template parameter JToken type is not valid. Expected ‘Boolean’. Actual ‘String’

This one is pretty straight forward – check the value you’re providing for your parameter. If it’s meant to a boolean ensure that you haven’t accidentally added quotes around it.

// Incorrect
"globalRedundancy": {
    "value": "false"
 }

// Correct
"globalRedundancy": {
    "value": false
 }

Decompilation failed with fatal error “Failed to read file:///C:/bicip….

When attempting to decompile an arm template with a non-json extension I received the following error:

PS E:\repos\bicep> az bicep decompile --files postgresmql.arm
accurate conversion is not possible.
If you would like to report any issues or inaccurate conversions, please see https://github.com/Azure/bicep/issues.
E:\repos\bicep\postgresmql.arm: Decompilation failed with fatal error "Failed to read file:///E:/repos/bicep/postgresmql.json"

The decompile command appears to force a .json extension and automatically renames the argument. The only way around it so far seems to be to rename your file. See the following github issue for more info: https://github.com/Azure/bicep/issues/1912

Thanks,

Chris

.Net 5.0 – This package is required for the Entity Framework Core Tools to work

I was trying to create a migration in a new project within a solution and received the following error:

Build started…
Build succeeded.
Your startup project ‘SubscriptionManagementGrpcService’ doesn’t reference Microsoft.EntityFrameworkCore.Design. This package is required for the Entity Framework Core Tools to work. Ensure your startup project is correct, install the package, and try again.

The error was a bit confusing because all of my migrations for the rest of the solution were still working and none of my other startup projects had Microsoft.EntityFrameworkCore.Design as a reference.

After a bit of comparing I realised that the other projects all referenced data projects that in turn referenced Microsoft.EntityFramework.Design. Adding the package reference to the subscription data library referenced by my GrpcService fixed the issue.

ElasticSearch on AWS – Anonymous is not authorized to perform es:ESHttpGet

Hi everyone,

I am trying out ElasticSearch on AWS and ran into the following error while trying to access the provided Kabana endpoint:

{"Message":"User: anonymous is not authorized to perform: es:ESHttpGet"}

This turned out to be pretty simply, I just needed to whitelist my IP. Go to your search domain in the aws console, click access and finally select “Modify access policy”:

Then all you need to do is add another statement that gives your current ip access:

{ 
"Version": "2012-10-17", 
"Statement": [
{
 "Effect": "Allow",
"Principal": {
 "AWS": "*"
},
"Action": [
"es:ESHttp*"
],
"Condition": {
"IpAddress": {
"aws:SourceIp": [
"192.0.2.0/24"
]
}
},
"Resource": "arn:aws:es:us-west-1:987654321098:domain/test-domain/*"
}
]
}

Feel free to comment below if you hit any issues, but I also found the following links pretty helpful:

Failed to load the development https certificate using docker and ocelot

Hey everyone,

I randomly started encountering the following error while using docker to host my Ocelot gateway:

Failed to load the development https certificate at ‘/root/.aspnet/https/ContentGateway.pfx’.

The solution ended up being to clean out as many temp files as possible, especially the generated certs:

  • Delete the following files: Delete the C:\Users{USER}\AppData\Roaming\ASP.NET\Https folder
  • Clean the solution. Delete the bin and obj folders (I just did this for the gateway project)
  • Restart visual studio/visual code

I’ll add an update if I can narrow down what caused the initial issue but for now this seems to work.

Element does not match nay field or property of Class – MongoDb and .net core

Hey everyone,

I ran into the following error today while searching MongoDb for an object:

Element ‘Tags’ does not match any field or property of class X.

The issue was that there were extra fields on the returned document that were not specified on the mapping target object. A bit of Googling revealed that there is a provided attribute that allows you to ignore all extra fields.

Simply add [BsonIgnoreExtraElements] to any relevant model definitions.

.Net Core Web Api Returning Binary File with No Headers Instead of Expected Response

Hey everyone,

A small issue I’ve run into while setting up a .net core web api microservice that also utilises a number of gRPC services. Symptoms were as follows:

Response Read via Fiddler
– HTTP/1.0 200 This buggy server did not return headers
– Value was binary and unable to be read

Server logs

03:59:23 DBG] Connection id “0HM01U963EUAR” accepted.

[03:59:23 DBG] Connection id “0HM01U963EUAR” sending FIN because: “The Socket transport’s send loop completed gracefully.”

The issue turned out to be that in appSettings.json the default kestrel endpoint had been set to utilise http2. Removing this immediately resolved the issue. It may also be worth double checking your launch settings, startup.cs and program.cs to ensure that nothing’s been overridden.

I expect that any similar routing issues would result in similar symptoms so hopefully this post will be able to save a few people a bit time!

Chris

Unable to find the target operating system for the project

Hi everyone,

I ran into the following error today after updating visual studio 2019 to version 16.6:

unable to find the target operating system for the project

I tried a fair few things to get this going again and I’m assuming they’re not all necessary, but I’ll list them just in case:
– Clean solution
– Close visual studio
– Delete .vs folder
– Ensure that docker-compose is set as startup project
– Edit each project’s .csproj file and ensure that the DockerDefaultTargetOS value is set: Linux
– Edit docker-compose.dcproj and ensure that DocketTargetOS is set
– Restart computer

If you’re able to narrow it down at all I’d be interested in hearing what the actual cause is!

Cheers,
Chris
