Schema error
originalMessageType 00557 rejected: feedback checked against the pre-release schema
Symptom
A feedback message on a corporate action (message 15) with originalMessageType = 00557 gives a schema error on originalMessageType.
Cause
Feedback schema 001.02 of the pre-release (July 2026) enumerated 0001a to 00556 and lacked 00557. The final Release 2027 (12 October 2026) fixed that: originalMessageType now lists the ten active messages, 00557 included. Whoever still gets this error checks against the pre-release feedback schema, which carries the same version number 001.02.
Fix
Check against the final feedback schema (tag v1.4.0) and build the feedback on the final release: afdDefinitionName is now VBPUO_Feedback_Message-001.00-VBPUO_Feedback_Message.
