Sudden 200 matrix error when idle

Description

Mirage was simply running in the foreground and the following error popped up.

(200, None)

Some details needed to identify the problem were lacking from the error popup in the version you ran. Please update to the last dev commit (the mirage -git AUR package should have it) and post the error if this occurs again.

I built mirage from source, and here's what I get:

(200, None)

Traceback (most recent call last):
  File "src/backend/matrix_client.py", line 410, in _start
    await self.sync_task
  File "/home/zapashcanon/.local/lib/python3.9/site-packages/nio/client/async_client.py", line 1155, in sync_forever
    sync_response = await self.sync(use_timeout, use_filter, since, full_state, presence)
  File "/home/zapashcanon/.local/lib/python3.9/site-packages/nio/client/async_client.py", line 1028, in sync
    response = await self._send(
  File "src/backend/matrix_client.py", line 266, in _send
    raise MatrixError.from_nio(response)
backend.errors.MatrixError: (200, None)

But that doesn't seem to bring much more information, so I'm wondering if I did something wrong...

Make sure you're on the right branch, run git checkout dev before building.

Ah indeed, that whas it. Thanks. Now I get a huge error, here's the beginning:

MatrixError: (200, None, 'unknown error', '{"next_batch":"

But what comes after is full of personal information that I don't want to share here and it's so huge that I don't want to filter it. Could you contact me and I'll send you the file ?

I also have this issue and it prevents the affected account's rooms from even loading (matrix.org and chatcloud.net). It has been a pain, because I made that chatcloud account to deal with the first matrix.org account breaking. Don't feel like making anymore new accounts after the second time, so I have to stick with talking to my friend from Element mobile. ><

This should fixed by https://github.com/poljar/matrix-nio/commit/1f17a20ca818c1c3a0c2e75fdc64da9c629eb5f9. This commit will be part of matrix-nio 0.18.5, which is to be officially released before tomorrow. It already is included in the new mirage 0.7.2 appimage and flatpaks. For manual installs, make sure to run pip3 install --user -Ur requirements.txt again before rebuilding.
