Git sync error (was: PSU will no longer start in Azure)


I don’t know what’s happened, but my app service running PSU no longer starts.

Before I tear the whole thing down and spin it up anew, can you tell me, @adam, if this exception means anything to you? I’ve even tried dropping the Azure SQL database and letting it re-populate it. The tables are there now, so PSU has definitely gotten far enough into the startup process to run the EF migrations.

I have found this in the PSU log file:

My GitHub PAT is still valid until January next year so it’s not that. Any thoughts?

OK this is just getting weirder and weirder.

PSU is up and running now, but getting that GitHub sync error every few minutes. It manifests in the UI like this:


I made a small change to a script and I can confirm that it is still syncing to GitHub! Just throwing this error for some reason every time it does so.

Closing this off because this discussion already exists:
