Unable to import app.py: Instance and class checks can only be used with @runtime_checkable protocols about langchain-serve

I was able to solve the issue by following the indications here https://docs.jina.ai/get-started/install/apple-silicon-m1-m2/ - I am running on an apple proc. Issue can be closed.
