Unable to create a GitHub token for the installation

[NewRunner2023]

I was following the instructions here: https://www.youtube.com/watch?v=39fl9Lusazo
"GitHub Automation with Quarkus by Guillaume Smet and Yoann Rodière"
and https://quarkiverse.github.io/quarkiverse-docs/quarkus-github-app/dev/create-github-app.html (this is where I got the fields that should be in the .env file from).

I have

1. made a GitHub app
2. installed it on my repo
3. wrote the Java code as described in the YouTube video (listens for new issues called osgi and closes them)
4. ran quarkus dev in my command line (everything starts fine)
5. made the issue in my repo, issue is called osgi

I can see:

It was suggested that maybe the problem is with the private key generated from the GitHub app.
To be honest I am not sure if I am using it correctly.
I downloaded the .pem file, and then used some Java code to extract the private key text from it.
Something like:

My .env file looks like

I know that https://quarkiverse.github.io/quarkiverse-docs/quarkus-github-app/dev/create-github-app.html has the QUARKUS_GITHUB_APP_PRIVATE_KEY spread over more than one line, but I tried this and Quarkus still started fine and I still got this error message about being unable to create a GitHub token.

When quarkus starts up and I go to my repo and make an incident I can see:

The stack trace comes after this.

If there is a problem with the QUARKUS_GITHUB_APP_PRIVATE_KEY value, I have noticed that Quarkus does not start. For example if you put double quotes around the value, or you have extra "" in it for carriage returns.

Where do I put the JSON web token ?
I went to https://docs.github.com/rest because it was mentioned in the stack trace, but I cannot find anything there about GitHub apps and JSON tokens.

Best Regards,
Trish.

Sorry for the late answer.

First a pem file is a text file so you should just open it with a text editor.

Also, the PEM file contains new lines and you shouldn't put everything on the same line.

Copy the exact content of the PEM file and add a \ at the end of each line, except for the last one.

See the documentation here: https://quarkiverse.github.io/quarkiverse-docs/quarkus-github-app/dev/create-github-app.html#_initialize_the_configuration .
