Language server crashes on some files with annotations #913

Open FredrikMeyer opened 3 years ago

FredrikMeyer commented 3 years ago

I'm using this library: https://github.com/awslabs/aws-lambda-powertools-python

And I have functions like this in my main.py file:

@tracer.capture_method
def time_consuming_maybe():
    <something>

However I get this error message in the logs whenever I visit a file containing these annotations:

I've tried updating both my editor plugin (Emacs LSP mode) and my Python language server (0.36.2)
