EXEMPTION_REGIME_NOT_SUPPORTED_IN_VERIFACTU
The given exemption reason corresponds to a special regime (REAEA, equivalence surcharge, cash basis, investment gold…), not to an art. 20-26 LIVA exemption. VeriFactu models it with clave_regimen, not operacion_exenta. Switch to the appropriate clave_regimen.

When it happens
A line uses an exemption_reason that names a special regime (EXENTA_ART_140 or one of the REGIMEN_ART_* values), not a VAT exemption. VeriFactu records special regimes with a regime key, not as exempt operations.
How to fix it
Remove that exemption_reason and set the matching regime_key on the line instead.
Retry
Not as is: the same request fails the same way. Fix the cause described above, then send the request again, under a new Idempotency-Key if the body changed.
