Adding a field with Combo Box input type and a list to the form in ArcGIS Field Maps Designer for a feature layer published with types, adds new types without name and id property and makes the feature layer inaccessible with the following errors returned: "Loading error This layer is broken or unavailable" and "Feature Type missing 'id' property."

Workaround

Note: Clearing types may impact other properties of the layer such as templates, symbology, etc.

To repair the service, update the types in a way that all have valid ids or clear the types to make the layer is accessible again. This can be done by sending an updateDefinition request and pass the correct types or clear the types by passing {"types" :[]} updateDefinition parameter in the request body. Since the REST endpoint is not accessible, another methods or tools can be used for this (e.g. Postman).
