WP_REST_Request return rest_no_route (404) for custom endpoint

I created a custom endpoint for the WordPress API-REST. I can access it normally via browser. But when I try to access it via WP_REST_Request, I get a message of "rest_no_route (404)"

<?php 

add_action( 'rest_api_init', 'custom_routes_rifa');

function custom_routes_rifa(){

    
    register_rest_route(
      'pluginrifa/v2', '/infos/', array(
        'methods'       => 'GET',
        'callback'      => 'api_rifa_infos',
        'show_in_index' => false
      )
    );

}

If I put /wp-json/pluginrifa/v2/infos/?rifa=140 in the browser everything works as it should, but the code below returns 404:

<?php
$request = new WP_REST_Request( 'GET', '/wp-json/pluginrifa/v2/infos' );
$request->set_query_params( [ 'rifa' => 140 ] );
$response = rest_do_request( $request );
$server = rest_get_server();
$data = $server->response_to_data( $response, false );
$json = wp_json_encode( $data );
          
$obj = json_decode($json);

I found this discussion Custom route endpoint for WP-REST API gives "code": "rest_no_route", error but none of the proposed solutions resolved, apart from apparently be something different, as it works via HTTP, but via WP_REST_Request it doesn't.

I found the problem, I had to replace:

<?php $request = new WP_REST_Request( 'GET', '/wp-json/pluginrifa/v2/infos' );

to

<?php $request = new WP_REST_Request( 'GET','/pluginrifa/v2/infos' );

/wp-json/ needs to be omitted from the request. I don't know why, but in several places on the internet, the examples for new WP_REST_Request are using wp-json in the URL. Perhaps, this has fallen on some WordPress update
