Additional Context

No response

Start at OAuth2Api.acceptOAuth2ConsentRequest() in the npm @ory/client SDK and reproduce the call with an object-valued id_token using the configuration shown. Trace where the consent request is serialized and verify the localStorage result; done means the object appears once rather than being duplicated.
