I am generating static images for polylines which is fetched from strava api. Now the issue is for some polylines the url is working fine but for others is shows the following error:

{
"message": "Not Authorized",
"error_detail": "Direct access not allowed"
}

URL: https://api.mapbox.com/styles/v1/mapbox/streets-v12/static/path-5+f44-0.5(paste_polyline_here)/auto/1000×1000?access_token=paste_access_token_here
