 * I still got the error message：
 * register_rest_route was called incorrectly. The REST API route definition for
   alo-easymail/v1/trkpxl 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 for more information. (
   This message was added in version 5.5.0.)
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Ferror-message-about-rest-api-2%2F%3Foutput_format%3Dmd&locale=en_US)
