How can one troubleshoot the error message "An active access token must be used to query information about the current user" in PHP?

The error message "An active access token must be used to query information about the current user" typically occurs when trying to access user-related information without a valid access token. To resolve this issue, you need to ensure that you have a valid access token before making any user-related queries. 

<?php

// Check if the access token is valid before querying user information
if($access_token) {
    // Make user-related queries here
} else {
    echo "Error: Access token is not valid.";
}

?>
