The error message indicates that there is an unrecognized feature 'document-domain' in the Permissions-Policy header.
The Permissions-Policy header is used to define the permissions of various browser features by specifying a list of allowed or disallowed features. However, the 'document-domain' feature does not exist or is not supported by the browser.
To resolve this issue, you should remove the 'document-domain' feature from the Permissions-Policy header and ensure that only recognized features are included. Be sure to consult the documentation of the browser you are targeting to verify the supported features for the Permissions-Policy header.
