Error message when trying to watch a co-op replay

[Sandro]

Steps to Reproduce:
1. Launch FAF Client
2. Click on Coop Missions tab
3. Choose FA Campaign
4. Choose Dawn
5. Choose "Solo"
6. Click the Replay button for any of the first 10 items

Expected
Replay would Launch

Actual
Error message pops up saying:
Bug Report
An error has occurred in the FAF client. It has been automatically reported.

When I launch Fiddler to try to learn more, the only message I see is attached.
When I try to connect to http[colon]//api.dev.faforever[dot]com/bugs with a browser, I get a 503 Service Temporarily Unavailable message, so I suspect my bug report has not been successfully delivered.

The logs made mention of some invalid json or something coming from here: https[colon]//github[dot]com/FAForever/client/blob/20bd703cf282b73eb2af90bc2af1ea6107b6ab94/src/coop/_coopwidget.py#L91. Unfortunately, I don't know the code well enough to have any idea what that means.

I've attached my forever.log file

Coop replays are broken. When I asked people to post the replays with error logs so it can be debugged I got excatly 0 reports. So don't expect this to be fixed soon.

Once it works again, coop leaderboards will be reset.

Is there anything more I can provide?

There will be an update on 29th, that will solve some of the replay issues. After that new testing will be needed. I ll update this forum thread viewtopic.php?f=42&t=11868 and post it on the whats ne page as well, what I need to test.
