Schema error on the maximum length of the IBAN, or a functional rejection by the fiduciary.
Cause
Release 2026 (001.04, also in v1.3.2) and the Release 2027 pre-release allow 10 characters: a full IBAN (Netherlands: 18 characters) is a schema error there. The final Release 2027 allows 34 characters, the international IBAN length, on the payment and on the creditor (issue #135). IBANs with spaces or lower case fall outside the expectation.
Fix
Deliver the IBAN contiguous in upper case and send a message with full IBANs as a Release 2027 message (001.05).
