What is wrong with my elasticsearch query ? Getting a expected end object error

I'm trying to do a elasticsearch query that does geolocation filter and does some matching on nested documents, but I'm getting this error whenever I add in the nested query.

"[bool] malformed query, expected [END_OBJECT] but found [FIELD_NAME]"
