API call getTransitionForPageTitle (no replies)

Hi,

I have a question about the HTML API call for the Transition report.
I did got it working for pageURL but pageTitle does return an error.
I did look on GitHUb but I did not find anything on this matter.

<result><error message="NoDataForAction"/></result>

API&method=Transitions.getTransitionsForPageTitle&pageTitle=Doe mee

In the documentation I did not find an example of an working example or a description how pageTitle should be filled.
Has the pageTitle te be URL encoded?

Thanks in advance.
Julia

PS. also if I want to export the data as TSV it returns in an error. Also for the example-call in the documentation:
