Guys, I\'m stuck, banging my head off the desk for the past few hours.
I am trying to consume a service, and I have 8 other functions that I call that are almost IDE
I had the same problem.
In soapUI preferences I checked the option Preferences → Editor Settings → Validate Responses and I received this information:
line 3027: Invalid decimal value: unexpected char '44'.
This solved my problem. Field contained wrong type value.
