WebApi 1.06 - VatNumber null in api-backend/Order/Search and api-frontend/Order/Details/ methods

CustomerId = 1 have this VatNumber

Id           KeyGroup  Key                    Value                EntityId  StoreId          CreatedOrUpdatedDateUTC
49869  Customer  VatNumber  IT33344455567  1        0                     2021-11-22 17:27:59..

But in JSON returned by https://xxxxx/api-backend/Order/Search?createdFromUtc=2021-11-21T18%3A16%3A14.848Z  --> the vat_number is NULL:

"items": [
        {
            "order_guid": "6b7dcdd7-e0fa-403d-918a-bd50a80073fc",
            "store_id": 1,

            "shipping_address_id": 225,

            "customer_tax_display_type_id": 10,
            "vat_number": null,
            "order_subtotal_incl_tax": 4.2700,
            "order_subtotal_excl_tax": 3.5000,

Also the method
https://xxxxx/api-frontend/Order/Details/104
return  "vat_number": null

It's probably a bug ...  ! ? !

Did you check the VatNumber on the order orderGuid = '6b7dcdd7-e0fa-403d-918a-bd50a80073fc', is it set? The methods which you describe do not take into account a customer VatNumber, only VatNumber which saved on the order table

VatNumber in order is null.

It would seem that the VatNumber, although present in the customer id = 1 (genericAttribute), is NOT included in the order.

what can be the reason?

P.S. I also tried to place a new order, but the problem persists.

How did you try to place the order?

The order is placed by standard checkout of Nop 4.40.4

It is not inserted by API

Please check the TaxSettings.EuVatEnabled setting, it should be true for placing the Customer.VatNumber to the order

TaxSettings.EuVatEnabled --> It is already TRUE   --> But in order VatNumber is null

All config TaxSettings:

Name  Value
taxsettings.taxbasedon  DefaultAddress
taxsettings.taxbasedonpickuppointaddress  False
taxsettings.taxdisplaytype  ExcludingTax
taxsettings.activetaxprovidersystemname  Tax.FixedOrByCountryStateZip

taxsettings.euvatallowvatexemption  False
taxsettings.euvatusewebservice  False
taxsettings.euvatassumevalid  False
taxsettings.euvatemailadminwhennewvatsubmitted  True
taxsettings.logerrors  False

do you have any other suggestions?

In this case, please check the status of the customer VatNumber in the customer details page (admin area), it should be valid

Ok, setting it as valid, now it works and the VatNumber is also evaluated in the Json Order.

THANKS !
