"Precondition Failed" when adding twitter handle to jazzhub account

Accepted answer

It needs to be url, in this format - http://twitter.com/<userid>
I will open a WI to have clear error message to indicate that.

I actually think the work item should be changed to modify the fields to just take the handles - and make that clear on the page.

Or even better, allow both options and users can decide which option to use.

Agreed. I've fallen for this one too. Now that I know what I'm supposed to enter I'll go update my twitter handle. :-)
