What it means
The scheme of the seller's and buyer's electronic addresses must be a code from the European Electronic Address Scheme (EAS) list, for example 0088 GLN, 0106 Dutch KvK number, 0208 Belgian company number, 0204 German Leitweg-ID, 9930 German VAT number, 0009 French SIRET or EM for an email address.
Why it matters
Codes are read by software, not by people. A value outside the agreed code list cannot be interpreted, so the recipient's system rejects the invoice even when the value looks sensible to a person.
How to fix it
Check the type of each electronic address on your company and customer records and use the EAS code, not a name such as "GLN" or "email". If you build the XML yourself, it is the schemeID of cbc:EndpointID (UBL) or of ram:URIID (CII). Ask your customer for their electronic address and scheme if you are not sure.
