Join dynamic github room not fully successful

I am trying to join a dynamic github issue room.
The room name is #github_yncyrydybyl_nothing_3:datanauten.de. That should point to https://github.com/yncyrydybyl/Nothing/issues/3.

The room is created. Topic and Avatar also fetched and set sucessfully. But then nothing in the rooms happens.
If I write messages these are not passed to the github issue. And when something is commented in the issue it also not shown in the room.

The log on creation looks like:
```

```

Start in Connections/GithubIssue.js around the org getter and syncIssueState, using the reported TypeError as the first lead. Trace how the uk.half-shot.matrix-hookshot.github.issue state event is handled through ConnectionManager and Bridge. Done means a dynamically created GitHub issue room remains connected and forwards messages in both directions.
