I have a feature service comprising of a feature class (outfalls), related table (inspections), and relationship class tying it all together. At first I was receiving the error "conversion failed when converting from a character string to unique identifier". I happened upon this solution and was able to insert the regex conditional statement into Survey123 Connect.
Now, when I submit records in S123, I get "String or binary data would be truncated. The statement has been terminated".
I've removed and replaced every single field and found that the FK is the only troublesome field.
I've attached my xls file to this post, as it seems as though many other have done the same when running into similar issues.
Thanks in advance,
MG
