InputValidationError in Proving Service

I’m using the Mysten proving service and getting this back:

proof: {
    "name": "InputValidationError",
    "message": "The audience is not supported"

What might be wrong?

the jwt token you passed in to call a prover has to be whitelisted by contacting us. you can check by pasting a jwt token in an box and find the aud value in payload. from what i see 123-abc is definitely not a valid google client id and not wihtelisted with us.
