Failed to match audience values error message from oauth2.token.handler.clientauth.jwt.validator;

[GeertsP]

Description:
Following up on the tutorial with the following link https://is.docs.wso2.com/en/latest/learn/private-key-jwt-client-authentication-for-oidc/ I have configured the service provider in Identity server 5.10 , created the necessary credentials and loaded these in wso2carbon.jks. I have created a signed JWT client token as follows:

{
"typ": "JWT",
"alg": "RS256",
"kid": "playground"
}
{
"iss": "PcxJbRWBA8dZCQbpxs56rFfNlFoa",
"sub": "PcxJbRWBA8dZCQbpxs56rFfNlFoa",
"exp": 1645969440,
"iat": 1643291040,
"jti": "14494155",
"aud": "https://localhost:9443/oauth2/token"

}

When after generating a client JWT token for this and run a curl against the identity server it gives a "failed to match audience values" message. Looking a the code documentation (I am no java programmer) it expects an "aud" value the same as the IS 5.10 server token endpoint. But I am supplying this so I don't understand the problem.
Am I doing something wrong or is this a bug?
