ACF REST API Custom Filter

Hi All,

I have a ACF REST API as below –
[
{
“id”: 1206,
“acf”: {
“user_id”: {
“ID”: 11,
“user_firstname”: “Test”,
“user_lastname”: “User”,
“nickname”: “testuser”,
“user_nicename”: “testuser”,
“display_name”: “Test User”,
“user_email”: “[email protected]”,
“user_url”: “”,
…………
},
“solution_id”: [
739,
496
],

}
}
]

I would like to query based on “user_email” filed inside the User_id object. Something like https://mysite.com/wp-json/acf/v3/[email protected]

I have below code in my theme function.php file.

function my_pre_get_posts( $query ) {

// do not modify queries in the admin
if( is_admin() ) {
return $query;
}

// only modify queries for ‘event’ post type
if( isset($query->query_vars[‘post_type’]) && $query->query_vars[‘post_type’] == ‘solutionaccess’ ) {

// allow the url to alter the query
if( isset($_GET[‘user_email’]) ) {

$query->set(‘meta_key’, ‘user_email’);
$query->set(‘meta_value’, $_GET[‘user_email’]);

}

}

// return
return $query;

}
add_action(‘pre_get_posts’, ‘my_pre_get_posts’);

This code is not filtering the response. Please suggest
