Troubleshooting & FAQ

Business rule (constraint) failed Business rules (invariants)
What it means
A FHIRPath rule in the profile or base FHIR was not satisfied. The message begins with the rule key and its human-readable text.
Why
Constraints encode rules that cardinality cannot, for example 'either A or B must be present'.
How to fix
Read the rule text in the message; it says what must be true. Change the reported location so it holds. Look up the key on the profile page under Invariants.
