Hello @kiran veerabatheni
Sorry for your experience and thanks for reaching out to here for it. I guess you miss the limitation of Face API. You should have received an email from Azure about the Face API limitation- https://learn.microsoft.com/en-us/azure/cognitive-services/cognitive-services-limited-access
Face service access is limited based on eligibility and usage criteria in order to support our Responsible AI principles. You got this error since what you are trying to call is now limited access to them because you have not been approved to use that capability. Face service is only available to Microsoft managed customers and partners. Please use the Face Recognition intake form to apply for access- aka.ms/facerecognition.
I hope this helps. Let me know if you have sent the form but still have this issue.
-Please kindly accept the answer if you feel helpful to support the community, thanks.
