TypeError: run_keyword() takes exactly 4 arguments (3 given)

The Keyword "Launch Application" fails with
TypeError: run_keyword() takes exactly 4 arguments (3 given)

This happens with versions 1.0.0 or 1.0.0.20181217.3.pre, with 0.0.0.20181204.3.pre everything was ok.

My setup is a bit complicated (White Library wrapped in PythonRemoteServer, tests run with Robot Framework Maven Plugin), but I believe the error also shows in a "normal" robot setup.

Robot Test file:

*** Settings ***

I was able to reproduce this with the PythonRemoteServer, Launch Application fails with "TypeError: run_keyword() missing 1 required positional argument: 'kwargs'". The error does not seem to occur with a direct library import.

Looks like there is an issue with run_keyword() in DynamicCore (it was not yet in use in 0.0.0.20181204.3.pre).

still happens with version 1.1.1

A fix has been merged to master and will be included in the next stable release. You can install the pre-release containing the fix with pip install -U --pre robotframework-whitelibrary.
