Nullpointer updating WikiPage from /api/jsonws
New Member Post: 1 Join Date: 4/20/20 Recent Posts
I'm trying to update a WikiPage from /api/jsonws invoking the /wiki.wikipage/update-page service on a Liferay Community Edition Portal 7.1.2 CE GA3
The following error trace is displayed on the console when the service is invoked:
Is this a bug in liferay, or is it a configuration issue? I have not made any changes to the code, nor am I writing any custom portlets. I am only trying to make use of the existing web api.
Anyone can help ?
Thanks
The following error trace is displayed on the console when the service is invoked:
