Error Evaluating MAP expression in previously working forms.

Error Evaluating MAP expression in previously working forms.

I have been having errors in my application saying the following:

Error in executing Set Variable task. Unable to update template variable xxxxx.

Error evaluating MAP expression : I was getting this error for a quickbook integration i have an open request for help on. Now this error just has appeared on an old form that was working as of last week and now not working... I'm beginning to wonder if i have an application problem rather than a coding problem going on. The new error has appears in my error log and is on the form SMS_Messages on Success script.   The error is happening on the following code:     sms_response = twilio.sms.send("Twilio_Toronto", mobile_string, input.Message); My twilio connection is set up. Edit access to support is already enabled. Thanks Matt
