The custom feature service submission url i snot compatible with this survey. (Fields not found in the feature service.)
Trying to publish a survey that will write records to a related table. I have successfully completed this before. I am following instructions found: How To: Create Survey123 for ArcGIS surveys that connect to non-federated ArcGIS Server services.
Feature service and table: https://services1.arcgis.com/a0b6GuyTJaCYvfET/arcgis/rest/services/Stream_Road_Crossing/FeatureServe...
It could be the field Date. That is a reserved word and has gotten me before with strange errors. Look at the types tab for a list of all reserved words.
I also see images in there. Do you have attachments turned on in the service?
Hope that helps.
