Suggestions for replicate_layout instructions about kicad_action_plugins

I am not really certain regarding the cause of the bug that you hit. It might be due to schematics not being in sync with layout or it might be something else. I've seen the bug before and I have a project where I can trigger it, so I'll address it.

Furthermore, I agree that improved error handling with nicer messages would be better, but I can only add this as the bug reports come in.

As for the more specific instructions, please submit the PR. All contributions are welcome.

I'm pretty sure now that it was due to a mismatch between the schematic and pcb, I wasn't aware the tool needed the footprints to be present, and in sync with the schematic. Once I updated the PCB with the newer parts, the error went away.

It sounds like you can already reproduce it, but I can provide you with a snapshot of the project which is able to replicate the issue if it helps.

I'll make a PR in the next day or so. Thanks once again, saved me hours of work today!

If it is not a problem for you to attach a project to public repository, then I would appreciate it. It might not help me, but at least I'll have the option when I'll start addressing the issue.
