I am looking for help resolving a Code 400 Error when trying to edit an existing record using Survey123. I receive the following error; "Send Error. This survey was not able to be sent due to the following error: Code 400 Unable to complete operation. Do you want to edit this survey?"
I am using a feature layer from ArcGIS Server. I successfully create the geometry in Collector. However, when I edit the attributes in Survey123 and then try to submit the edited record, I receive the Code 400 error. Any help would be greatly appreciated.
