UBL not valid

[krosoftware]

Hello
generated UBL invoice is not valid. I'm using this validator: https://www.ubl.be/validator/
and here are the errors: https://i.postimg.cc/9FgdZZ4c/Screenshot-2023-02-17-090848.png
I'm using curl from this page: https://invoice-generator.com/developers to generate invoice

  -d from="Invoiced, Inc.%0AVAT ID: 1234" \
  -d to="Jared%0AVAT ID: 4567" \
