Your data is missing a permitted-development-rights.

The Article 4 direction area guidance explains how to fix the issue:

A list of the permitted development rights withdrawn by the article 4 direction.

Separate the rights in the list using semicolons.

Only use rights from our permitted development right dataset. If the area withdraws a permitted development right that is not in our dataset, email digitalland@communities.gov.uk.
