I have had this Send Error Code 1000 before and been able to do some edits to the feature service to increase the field length both in Survey123 and the feature service itself. However for one specific questions it doesn't seem to be working.
The specific question I am having trouble with is a select_multiple type of question I managed to increase the field length ( right now it is at 10,000 characters) for it but when I try to submit it it only allows me to send if I check only one of the options not multiple.
I have other questions in my survey that are select_multiple and they have been working fine once i increased the number of characters allowed.
I have attached the question I am having trouble with.
Thanks for the help!
