Why am I getting error code 4124 – EC_PEID_NOT_MATCHED_WITH_HEADER?

Error 4124 – EC_PEID_NOT_MATCHED_WITH_HEADER indicates that the principal entity ID (PEID) used in the request does not match the sender ID (header) it is associated with. This misalignment prevents successful message delivery.

Why it occurs

This error typically results from configuration issues on the DLT platform, where the PEID and header are not properly linked. It may also be due to incorrect values passed in the request.

Steps to resolve the issue

1. Verify PEID and header alignment on the DLT portal

– Log in to your DLT portal and confirm that the PEID is correctly mapped to the specified header.
– If the mapping is incorrect, update your request with the matching PEID and header combination registered on the DLT platform.

2. Contact Support if alignment is correct

– If the PEID and header are correctly configured but you still receive this error, take a screenshot from your DLT portal showing their association.
– Send the screenshot and a detailed issue description to our support team at [email protected].
