Opening a survey with a begin repeat, a relevant expression, and a minimal appearance in the ArcGIS Survey123 web app 3.16 returns the error message, "Error: Initializing form...TypeError: this.form.repeatPathPrefixes is not iterable".

Workaround

• If the survey is published from ArcGIS Survey123 Connect 3.15 or older, in the settings of the survey in the ArcGIS Survey123 website, select the Use the version the survey was published with (3.1x) option under the Web app version section.
• If the survey is published from ArcGIS Survey123 Connect 3.16, remove the minimal appearance from the begin repeat, or remove the relevant expression and republish the survey.
