Code 400: Unable to add feature service layer definition

Question

I am having trouble publishing my survey as I get a code 400 from Survey 123 Connect whenever I try to publish (see below). The survey has already been published but I would like to update it with the new changes that have been made.

The field in question "disclaimer_arl_fss" is located at the bottom of the survey in the survey tab and is a "text" type. How can I fix this issue and successfully publish my survey?

Setting that field to null worked in my case. Makes the error seem all the weirder though, since no view service was ever being modified...

You can set the bind esri field column to null then you can have a field in your form that is not in the hosted service.  If not needed in the data this works great.

You should be able to add a field ok though.  It sounds like OP is pointing to a view and not a layer.  Seems like something else may be up.

Man, what perfect timing. I too am having this problem! It started yesterday when I attempted to add a Note field to my survey. A field that requires NO user input, yet wants to create a new field in the survey database. I've added fields to this survey using Survey123 Connect before, but attempting to add this one results in the same error Mike is getting. If I remove the Note field I've added, the error goes away.

According to other answers I've seen elsewhere I've chosen Save As... in my spreadsheet and given it a different name in a different location. Then using Survey123 Connect to open that new spreadsheet, I was able to publish and generate a new survey. This works, even with the offending Note field. But this is definitely NOT a preferred method. It doesn't retain any submitted surveys, if you're modifying a production survey (which you probably shouldn't be doing anyway) and it breaks any maps or views that you may have created to analyze data from the original survey. (Not to mention anything that relied on webhooks from the original survey, which now has to be recreated in the new survey...)

It still boggles my mind that there are two products to create surveys for Survey123 and they are not compatible. The moment you touch a survey with Survey123 Connect, you can no longer use the web based survey editor. These two things should be cross compatible. This needs to be fixed. It's not a feature, it's a bug.
