I am trying to create access token but I got the internal service error response. I have passed the exact endpoints and tested it from different media i.e Postman, Laravel Package, and Mtn Developer Sandbox Request Sender
{
"statusCode": 500,
"message": "Internal server error",
"activityId": "9b410efe-42f8-47fb-8292-55a86dbbb067"
}
