i have a problem

[Solovic2]

hello sir ,
when i use first step when i call youtube/auth , after signing in , it redirect back and show me this error

the error is : " GuzzleHttp\Exception\ClientException
Client error: POST https://oauth2.googleapis.com/token resulted in a 400 Bad Request response: { "error": "redirect_uri_mismatch", "error_description": "Bad Request" } " .

i put the second route with method ( callback ) and the error i think from third line

public function callback(Request $request){

$redirect_url ='http://localhost/proj/public/youtube/callback';
$video = puplic_path('video\1.mp4');    // i made a folder called video and put one from my computer

$youtube = Youtube::setRedirectUrl($redirect_url)->upload($video,[]);`

// Get uploaded video id
return   $video_id = $youtube->uploadedVideoId();

}
what should i do ?

thanks sir .
