In ArcGIS Collector, an error message, "Attempted to use invalid JSON error" is returned when the feature with a date range domain is added to subtypes.

Workaround

Below are the possible workarounds:

• Remove the date domain from the subtypes (can still keep the range domain for the Date field, but is removed from subtypes).
• Change the date domain to a coded-value domain.
• Remove the date domain.
• Publish to Portal for ArcGIS.
