Could not Find a Property Named 'Property'

Symptom

When creating, editing or viewing a sample, or running a flow, you may encounter the following error:

Could not find a property named 'property'

Where 'property' is a data set field's name, like statecodename.

Cause

This happens because a field (that is required) is invalid or missing.

Solution

The solution is to remove the field (in the error) from the data set, or remove any reference to it. A field can be referenced in the Flow builder, the Condition builder or the Template builder.
