Problem with REST API

Hello,
i have the following problem:

Warning: The Optimization Detective REST API endpoint is unavailable

To collect URL Metrics from visitors the REST API must be available to unauthenticated users. Specifically, visitors must be able to perform a POST request to the /optimization-detective/v1/url-metrics:store endpoint.

You may have a plugin active or server configuration which restricts access to logged-in users. Unauthenticated access must be restored in order for Optimization Detective to work.

The REST API returned with an HTTP status of 403 Forbidden.

Unerlaubte REST-Anfragen unterbinden: ist deaktiviert!

i put this in the functions.php

// Erlaube nicht-authentifizierten Zugriff auf den Optimization Detective REST-API-Endpunkt
add_filter( ‘rest_authentication_errors’, function( $result ) {
$request_uri = $_SERVER[‘REQUEST_URI’] ?? ”;

if ( strpos( $request_uri, '/wp-json/optimization-detective/v1/url-metrics:store' ) !== false ) {
    return true; // Zugriff erlauben
}

return $result;

});
