Nice catch! This is a different error from what we have encountered before. I think I have seen this in my log at some point, but did not find anything in the code that could explain this. I will have a look tomorrow.

It would be nice if we could add the class and/or instance name of the container id to the log output, so that we may find a pattern to the workflow that causes this and be able to reproduce the issue.

Is there anything that you can remember from the workflow you have that could have triggered this?

I will try to add a safe-guard to this case tomorrow.

No. I was in a lengthy call and I think I've been using the mouse mostly. After a break I came back to my machine and the shortcuts that I have set up for i3ipc-dynamic-tiling didn't work anymore. So, no unfortunately I cannot recall the exact moment when this happened.
