To Reproduce Do occ app:update --all on an NC25 instance with beta channel; yields

mediadc new version available: 0.3.0-beta.1
An unhandled exception has been thrown:

You may use your browser or the occ upgrade command to do the upgrade

Expected behavior No "unhandled exception".

Additional context php occ upgrade resolves the issue.
