Ycmd wrong command 'GetType'

[noxdafox]

Every time I load a new Python file I get this error in the log.

It seems ycmd is sending a wrong command to the server.

During handling of the above exception, another exception occurred:

ycmd and emacs-ycmd are up to date.

The error is probably from ycmd-eldoc, you have it enabled right? Don't worry about it. It's normal. ycmd-eldoc is sending a GetType request if a completion request is not returning any information and if the filetype completer does not support GetType, like python we disable the GetType request for that buffer. But get this error once for a buffer. We could ask the server if GetType is supported before sending the request, so that the error does not pop up. Would be less confusing I guess. I have an experimental branch with this and I'll send a PR as soon as I have time for it.

[noxdafox]

Yes I have it enabled.

I started investigating this issue because all of a sudden I stopped getting parameters completion on ycmd. It used to complete a function altogether with its parameters and now the only thing it reports is the function name.

I can't really wrap my mind about this issue.

Also using C-h in company completion shows a no documentation available message in the minibuffer.

@noxdafox Regarding parameter completion in python see #431

ycmd (i guess jedi backand) chaged the format for python functions. I missed it since I'm not writing much python at the moment.
