We're running into an error when trying to create an estimate through rest api. This is the payload -

  },

    "items": [
      {
        "taxCode": "111",

  },
  "billingAddress_attention": "attention",
  "entity": {
    "id": "2343"
  }
}

But we get the error -

USER_ERROR: Error while accessing a resource. Please enter value(s) for: Phone.

The payload has Phone number values for

billPhone

as well as both the addressBook objects and the shipping and billing addresses. I've checked the estimate transaction form and there is no mandatory field for Phone. What am I doing wrong here?

addrPhone

rather than

addrphone

?
