@HaaiHenkie yes, I’m sure it’s related to PyCharm (which is the same as Intellij + Python plugin)… as you can see in the stack trace attached, all the error trace comes from com.jetbrains.python, whereas the language server is in a completely different namespace (which doesn’t even appear there).

What I think is happening is that because the language server creates a reference to a Python file then the Python plugin tries to take over to improve the info and fails in the middle of it – I still haven’t been able to debug it properly on why it does that (possibly the reference that is created doesn’t please the Python plugin as it expects) as I’m finishing something else, but this is high on my priority list and I plan on tackle that before the next release.
