Error Message

When working on ArcGIS Online hosted feature service layers in Collector for ArcGIS with an iOS (Aurora), the layers do not draw, and a warning message appears on the layer list indicating "The layer could not be loaded". A click on the warning returns the following error message:

Error:

Cause

The problem occurs due to an issue with the domain as stated in the error message. The domain field type does not match the assigned field. In this case, a domain with the short integer type is assigned to a double field type.
