Need help regarding defining a GEO Search using Firebase and the Firebase Typesense Extension. When we execute the following:

results = await client.collection('events').documents.search(
  {
    'q'         : '*',
    'query_by'  : 'title',
    'per_page'  : '250',
    'filter_by' : 'location:(37.71,121.91, 30 mi)'
  },

We receive the error: SEVERE: ClientException: Connection closed before full header was received. and a URL which I removed for privacy. We hard coded the lat/long in the filter just to get results but all we get is the error The events collection in Firebase has as a field called location with a datatype of geopoint populated with lat/long for an event. We can filter_by successfully with any field but location. Any pointers? Any sample code? Thoughts here? Thanks.
