Solutions

1. Fix the condition reported by the error: unresolved RecordComponent {}
2. Check the throwing call site and ensure its documented preconditions (argument values, types, environment, or configuration) are satisfied before the call.

Example fix

Validate inputs and environment so that the failing condition does not occur: unresolved RecordComponent {}

When it happens
