I need to update the product custom_attributes. I use the rest API and XML (this is important) in the Postman. But I get an error message (see Attachments). If I try to update only one custom_attributes, everything is fine. The error is displayed when I update more than one custom_attributes (see Attachments). In JSON format everything is fine, but I have to use XML.
Thanks for any ideas
