"Undefined" an inaccessible hosted feature layer error

Question

I have a point hosted feature layer that is being used as source data for a view layer. The view layer is referenced by a web map and app. I went to edit some attributes in the hosted feature layer (source) and was unable to access the data. An "! undefined" error is associated with the feature dataset (see screencap below)

Does anyone know why or how this happens, and the best path to fixing it? The web app is embedded in a public-facing website, so a fix would need to be approached cautiously so as to have minimal downtime with the ExB app. Thanks,

I have a FL created in Survey123 connect that's doing the same thing; when the "! undefined" error appeared last week, I was able to go into Settings and Rebuild Spatial Indexes to fix it, but now Settings is greyed out.

You can reach out to technical support and leave this post up. They can search related incidents and internal knowledge articles, as well as actively investigate the issue.

The times I have seen this issue it has come from bad data published like the csv example, some post-publishing configuration like updating the definition using AGOL assistant, or something finicky on the backend.

View layers can allow for feature editing. It's very useful in some scenarios e.g. allowing public to submit data via survey123 but allow for no features to be visible on the view. One way data.

Hey Rhett!

Thanks for the response. Very interesting about the different browsers. I will test that out in the future!

In this instance, I'm using Edge, and also got the same issue using Safari. Another Admin in the organization confirmed they got the error too (I'm unsure which browser). The error only applies to the source and not the view.
