Hi, how do add additional keys to .well-known/jwks.json i'm aware of this documentation https://www.ory.sh/docs/hydra/jwks which says to run the command

ory patch oauth2-config $YOUR_PROJECT_ID \
  --add '/webfinger/jwks/broadcast_keys/-="custom_keyset"'

however when i run that i get the error: The request was malformed or contained invalid parameters json: cannot unmarshal object into Go struct field NormalizedProjectRevision.hydra_webfinger_jwks_broadcast_keys of type string
