PS 8.0.1 Webservice generates wrong xml content for customers schema=blank

[ivailoi1974]

Server software version: Apache

PHP version: 8.1.27
PrestaShop version: 8.1.0
MySQL version: 10.6.12-MariaDB
MySQL engine: InnoDB
MySQL driver: DbPDO

 

Using the webservice to add manually generated xml for a new customer works

Trying to get a blank schema and fill the needed fields does not work.

The response contains the schema, but there is an error in the associations block. Here is what I get:
 

<?xml version="1.0" encoding="UTF-8"?>

<prestashop xmlns:xlink="http://www.w3.org/1999/xlink">

<customer>

<id><![CDATA[]]></id>

<associations>

<groups>

<group>

<0><![CDATA[]]></0>

</group>

</groups>

</associations>

</customer>

</prestashop>

the first group has a title 0 instead of id.

<id><![CDATA[ ]]></id> should be OK

Any suggestion for fixing this problem?
