Hello @Sretthapon Rattanasri
Thanks for reaching out to us. Microsoft facial recognition services are Limited Access in order to help prevent the misuse of the services in accordance with our AI Principles and facial recognition principles.
Since the announcement on June 11th, 2020, Azure face recognition services are strictly prohibited for use by or for U.S. police departments.
Come back to your issue, there is a limit access for faceId property. To use this feature, you can change returnFaceId=true to returnFaceId=false. If you do need FaceId, please apply for the access -
Customers and partners who wish to use Limited Access features of the Face API, including Face identification and Face verification, are required to register for access by submitting a registration form. The Face Detection operation is available without registration.
