Issue wihile submitting B2B Invoice

Dear Team ,
While submitting a B2B invoice in the production environment, I encountered an error.
The customer has a valid VAT number — it starts with 3, ends with 3, and is exactly 15 digits long, as required.

Could someone help me understand what might be causing this issue?

@Mohanad please check the UBL tag, Buyer’s VAT Number should be provided under
<cac:AccountingCustomerParty / cac:Party / cac:PartyTaxScheme / cbc:CompanyID>
