/talks Api issue. 500 Internal Server error

I'm on the Pro plan and trying to call the /talks API via Postman using a valid Authorization header and a tested JSON payload.
However, I consistently receive a 500 Internal Server Error with the following message in the response body:
vbnet
CopyEdit
TypeError: Converting circular structure to JSON
--> starting at object with constructor 'TLSSocket'
| property 'parser' -> object with constructor 'HTTPParser'
--- property 'socket' closes the circle
I’ve already:
Verified my API key format (using Basic Auth with Base64-encoded credentials)
Used known-good sample images (or-roman.jpg and default-character.png)
Tested in both Postman and curl
Could you please investigate this server-side error?

Thank you, do let me know if it is fixed as I have a deadline to complete with the communication between D-ID and another product using your Api key.
