Hello,
i have an application with a geoprocessing tool widget which I tried to show an output message for the users once its finished. but every time it's done, the output text is Error.
I've spent a few good hours, trying dozens of things to try and understand what the problem is.
So eventually I got it sorted. I managed to find the solution and after so much frustration and attempts, I thought this might help someone in the future.
I was extremely surprised to see no one have noticed this before tho. I found a few similar posts but not with the same issue.
