Submission url compatibility error

[FranklinAlexander]

I am getting the following error:

Survey123 error 400 "custom feature service submission url is not compatible..."

even though according to esri documentation my submission url is correct.:

How To: Create Survey123 for ArcGIS surveys that connect to non-federated ArcGIS Server services

The id in the submission url matches the id of the survey which I got from the survey url as instructed in the above doc.

Url to the survey

https://survey123.arcgis.com/share/+ surveyId 

submission url format I am using:

ArcGIS Portal Directory + surveyID

Is there some other reason I could be getting this error?

Thanks

Hi Franklin,

The submission url you referred for portal should not end with surveyID, it should the the item ID you added from the feature service(step 1-4). Could you double check to see if you are using the correct item ID?
