afdDefinitionVersion incorrect (001.04 versus 001.05)
Symptom
Schema error 'must be equal to one of the allowed values' on afdDefinitionVersion, or the receiver validates against the wrong schema and reports unknown fields.
Cause
The message was built according to Release 2026 (001.04) but states 001.05, or the reverse. Release 2026 v1.3.1 corrected the '(prerelease)' label in all schemas.
Fix
Fill the schema version the message was actually built with and agree per link which release is active.
Wrong and right
Wrong
{ "afdDefinitionVersion": "001.04 (prerelease)" }
Right
{ "afdDefinitionVersion": "001.05" }
