issues about invoke_tools

[nbllxbl]

My invoke_tools function can't get right outputs, but when I replace "regex = create_function_regex(wapi_start, api_stop)" line in function with regex = create_function_regex(), things get better.
I don't know why but it does work.

api_stop should be "]" rather than " ]", which leads to different regex so the tools are not called.
