Problem when migration SignInApple auth/usermigrationinfo invalid request

I'm facing the following issue when I try to use the API https://appleid.apple.com/auth/usermigrationinfo

I want to know if my request is valid 
POST /auth/usermigrationinfo HTTP/1.1
Host: appleid.apple.com
Content-Type: application/x-www-form-urlencoded
Authorization: Bearer (Bearer generated)
sub=(Team ID 10 letters)
target=(Team ID Target 10 letters)
client_id=Bundle id
client_secret= Secret generated with private key

I have already transferred my app to another owner

This is my output
{
    "error": "invalid_request"
}

Thanks & regards
