Description

Upon sending a custom state event to alter the E2E key rotation, the device that sent the event is no longer unable to send messages. The event sent was :
{ "algorithm": "m.megolm.v1.aes-sha2", "rotation_period_ms": 604800, "rotation_period_msgs": 10 }. With the state key left as blank and event type set to m.room.encryption. Even trying to send a message with the original setting sand more data such as the sender, room ID the issues persisted.

Sending /discrdsession yields the following :

However when inspecting the room settings.

Even leaving and re-joining the room did not fix this issue.

This is the following error produced by the developer console when attempting the send or resend the messages.

Any other device can still send messages fine, and so can the other person within the room.

Steps to reproduce

-Set up a room with 2 people
-Enable encryption
-Use dev tools to send the following custom event { "algorithm": "m.megolm.v1.aes-sha2", "rotation_period_ms": 604800, "rotation_period_msgs": 10 } with m.room.encryption as the event type.
-Attempt to send a message
-Messages will send fine until the rotation conditions I think? Or after a few hours depending on the rotation period.

Describe how what happens differs from what you expected.

Log: not sent.

From what I can tell, the JS SDK doesn't currently set any value for rotation_period_ms or rotation_period_msgs, so I would guess there is a bug in its support for these options.

the problem is that riot-web bails out if there are any changes to the e2e config, with:

index.js:962 Ignoring m.room.encryption event which requests a change of config in !UCnwUWwIKhcpaPTHtR:sw1v.org

Ideally I think we'd spec that some changes to e2e config were permissible, but it seems like a bit of a can of worms.

I'm going to close this issue for now as we cannot reproduce it and functionality has changed since it's been filed. Please open a new issue with a rageshake if you are still experiencing the problem.

The functionality here hasn't changed - altering the key rotation parameters still causes the room to break when it shouldn't.
