Fix invalid key error #2332

Open corrideat opened 2 weeks ago

corrideat commented 2 weeks ago

Problem

Just before merging PR #2294, a ChelErrorSignatureKeyUnauthorized error was thrown. This is a serious error indicating key management issues that will result in degraded user experience.

The error manifested in the second attempt of the pre-merge GitHub action run.

From the corresponding logs, the following could be inferred:

Error

Problem diagnosis

When user2 votes on the proposal to remove userBot, it sends a message to the #general chatroom as the proposal passes.

A previous test was for user2 to join the group, leave and then re-join. It seems that, at least from the perspective of user1 and userBot (need to confirm whether this also was the case for user2), the action to re-join the #general chatroom was never processed (this could be due to a processing error or due to it never having been sent).

The video of the run, at around the 1:00 mark, shows that user2 has left #general but hasn't rejoined.

As a result, when user2 sends this message, the inner payload uses an inner signing key that has been revoked (when user2 left the group). This triggers the error in question, as expected. The correct behaviour in this case would be to make sure that user2 rejoins the #general chatroom when re-joining a group, and that this action is correctly processed by all members.

Solution

As noted, the error is expected due to another underlying error (user2 not rejoining the #general chatroom). The solution is to diagnose why this happened and address this situation so that it doesn't happen.
