Probable cause

The XML canonicalisation used is not Exclusive C14N 1.0. ERPly Pro forces this canonicalisation; a failure here indicates a misaligned signxml version.

How to fix

• Flag this as high severity to the ERPly Pro team: the signing layer must enforce Exclusive C14N 1.0.
• This is not an error the tenant can fix.
