Without change the SBT file, I get a "java.io.IOException: Error writing to server" exception

Hello!

I want to upload the JAR artifact to GitHub packages with the plugin. The plugin definitely did work in the past. However, sometimes I just get this exception:
java.io.IOException: Error writing to server

I set the "GIT_TOKEN" environment variable:

The corresponding build.sbt file looks like this

publishMavenStyle:=true
githubOwner := "<theOwner>"
githubRepository := "<theRepo>"
githubTokenSource := TokenSource.Environment("GITHUB_TOKEN")

When I run "sbt publish", it sometimes works, sometimes I get the mentioned error. Are there logs (maybe in GitHub) where a more detailed error description is available? For example, the GitHub Token is valid, otherwise the upload would have never worked. Also, I need a reliable configuration of the plugin, because we want to use SBT in a pipeline (in Azure).

Thank you for your help!
Kind regards, LT

I seem to be experiencing a similar. I copied a working configuration from one project to a new project and now I am unable to publish with an HTTP 422 error.

Similiar 422 situation here.
This plugin is the best approach, but if you can't diagnose it a workaround is to use mvn deploy:deploy-file.

I've documented how to create a .sbt task that works locally and inside Github Actions
