ExApp upgrade fails due to a init status report rejected as unauthorized #803
Description
Describe the bug
Upgrade of an ExApp context_chat_backend failed to automatically set everything up. The "version" key in the logs show the version of that app.
It doesn't seem to be an issue with the ex-app itself since /init is not handled in there.
A restart of the ex-app's container fixes the issue, maybe it was called too early?
