Schema error

originalMessageId missing in feedback or resend

Symptom

Feedback message is itself rejected: 'must have required property originalMessageId'. On a resend (message function 54) without originalMessageId the receiver cannot see which message was sent again; the validator gives a warning for that.

Cause

In the feedback schema originalMessageId is mandatory. In ordinary messages it is optional, also with message function 54 (sending unchanged content again): the standard does not prescribe the reference there, but without it the resend cannot be linked to the original message.

Fix

Fill the messageId of the message the feedback relates to, or of the message that is sent again or replaced.

{ "commonFunctional": [ { "entityType": "default", "function": "23", "statusType": "8" } ] }

{ "commonFunctional": [ { "entityType": "default", "function": "23", "statusType": "8", "originalMessageId": "0001A-20260930-000001" } ] }
