Publishing Survey 123 error 400: Unable to add feature service layer definition.

[JCasebolt]

Hello, I am trying to publish a survey in Survey123 and I keep getting the error code 400: Unable to add feature service layer definition. I've tried closing out and re-opening the survey. I cannot find what this error means. Any help is much appreciated!

Is the survey being published to ArcGIS Online or ArcGIS Enterprise. Additionally, does the survey contain questions that have identical names.

 The survey is being published on ArcGIS Online. I ended up calling ESRI customer service and figured out it was a bug. I just had to make a copy of the survey and then I was able to publish it.
