Testing activities VerifyExpression ends with error 'An error ocurred while sending the request'

Hi @jucgonza

This looks strange.

Few things that you can try

  1. Recreate the activity and re publish
  2. Check the Windows application logs(Event viewer). May be there is something unusual happening
  3. Revalidate your expression if there is some null reference or that value is not initialized for any of the cases

And in Expression just to make sure use ‘Not’ instead of ‘!’(Not)

cheers
