Unable to find document file:///home/m/Documents/bottletest/hello.py

Means there is no document in the document table and hence no analysis. By any chance, does it work if project is some other location?

Also, null reference means _indexManager was not created and hence we didn't get InitializedAsync yet - requests leaked through before initialization is fully done.
