Survey email not found - ERR0005
As a respondent taking a survey, if you see the error "Respondent email was not found when saving" (ERR0005), here are things that could be causing this.
Survey is not collecting email
Ensure your survey has a question that collects the respondent email ( how-to guide), and uses two-way sync to link the value to the Email panel property.
Disqualify logic before collecting email
If you have logic set up in your survey, and you disqualify a respondent before collecting their email, you will get an error.
Move the question collecting the email before any disqualifying questions.
