#       v jump to this

# ...

Apparently the put_document resp. m_text_document__did_open is not called (only for sources installed in my virtual env, my development files are working), where I have no clue how this is invoked...

I am using neovim with LanguageClient-neovim plugin

[gatesn]

@diefans can you paste more of the log? Ideally running pyls with -vv as an argument

[diefans]

The get doc log is inserted by myself. When everything works, put_document is called when neovim jumps to the definition, which is missing here (no put doc log)...
