sync.app_credentials_rejected

The panel cannot sign in to GitHub

A mevcore app hosting error at the “code upload” stage.

What it means

GitHub rejected the GitHub App keys configured in the panel (the key was replaced or the App settings changed).

The error happened while mevcore was fetching the code from the repository or archive, before dependencies were installed. The current version of the app keeps running.

Typical causes

The branch was deleted or renamed, or the repository is no longer accessible
mevcore's access to GitHub was revoked or expired
The archive is damaged or larger than the limit

How to fix it on mevcore

This is not a problem with your repository and only an administrator can fix it; deployments from GitHub work again once the keys are updated.

1 Open the app in the mevcore panel: the Problems card on the overview shows this error and the log line it was found in.
2 After the fix, deploy again. If it fails again, the log ends with [mevcore] lines naming the new error code.
3 The "Ask AI" button next to the error prepares a request for ChatGPT or Claude: the error code, the end of the log without secrets and the app settings.
