# REST API – PHP Error log

 * I have rolled back to 4.2. I’m seeing this in my PHP Error log. Does this indicate
   anything helpful?
 * Notice: register_rest_route was called **incorrectly**. The REST API route definition
   for `instant-images/test` is missing the required `permission_callback` argument.
   For REST API routes that are intended to be public, use `__return_true` as the
   permission callback. Please see [Debugging in WordPress](https://wordpress.org/support/article/debugging-in-wordpress/)
   for more information. (This message was added in version 5.5.0.) in /home/redacted/
   public_html/mayur.ca/wp-includes/functions.php on line 5229
