Hello Vamshi, occasion_data.rsvp is currently not a field which is supported in sub queries. The way to retrieve the list of rsvps for a messsage is either through the LIQL query mentioned above:  "SELECT * FROM rsvps WHERE message.id = '<msgid>'" or using the following JSON in API call ``` {   "rsvps": {     "fields": [       "rsvp_response",       "user"     ],     "constraints": [       {         "message.id": {           "=": "<msgid>"         }       }     ]   } } ``` ...
