Can't update registered office address

After I have authorized the client program I get a token.
I successfully created transaction as well.
But when I try to create a registered office address resource I am facing issue.
If I follow the description in Manipulate Company Data (API Filing): Create a registered office address resource
I get an error:
“errors”: [
“error”: “required”,
“location”: “company_number”,
“location_type”: “json-path”,
“type”: “ch:validation”

If I put the company_number into the json, I got internal server error.
What could be the problem?

The request’s body is the following (without company number):
“premise”: “1”,
“address_line_1”: “Companies House 15”,
“address_line_2”: “Crownway”,
“country”: “United Kingdom”,
“locality”: “Cardiff”,
“postal_code”: “CF14 3UZ”,
“reference_etag”: “da194f5f72cac9a1b82ef6d325af7f880a303e3b”

Ok can you Whatsapp me , I will teach you that and resolve the error
