I've been working to create a set surveys, all linked to a set of base points in FieldMaps.
So far, here is what I've done:
This worked for three out of four my surveys. The URL in my pop-up will not open the Transect form. It will open survey123, but then it just spins until it crashes. I have tried multiple devices and none of them work. When I open the form directly from the Survey123 App and manually enter the PointID, I am able to fill out my survey and submit to outbox, but the survey will not send. When it is trying to submit the pop-up/loading screen flashes through all of the related tables and layers, so it appears to be communicating with my feature layer. After trying to send for a few seconds, it stops with an error saying, "Operation Rolled Back." I set up the other three surveys exactly the same, so I am pretty stumped.
Looks like you are using my trick so I hope you saw this post even though its dated now https://community.esri.com/t5/arcgis-survey123-questions/mapping-with-survey123-within-a-polygon-or-...
It is way easier to download the GDB of each form and then simply copy paste into the master GDB. Then you do not have to recreate all the 123 relates. Much faster and more reliable.
My guess here is you missed copying something over for that form. A related table, attachments table maybe, possibly domains. Without seeing the form or URL I would start there. I would suggest starting over really and use the copy paste method.
Your error almost looks like it does not like PointID. Maybe it is a number or short text or something?
Hope that helps some
