Getting CORS Error (Internal server error)

I am getting error while using talk stream api.

Even after using fetch with retries, I am getting CORS error. Regenerated the key multiple times..

Error message is (from talk response)

Response {type: 'cors', url: 'https://api.d-id.com/talks/streams/strm_72355fjoYjWAntHq9hC32', redirected: false, status: 500, ok: false, …}

Can you check and revert back. It was working previously (last week as well).

Your prompt response would be highly appreciated.
