Apache Pinot

Does anyone have a working example of using anything other than the stPoint &amp; toSphericalGeography functions?

you can read this blog <https://eng.uber.com/orders-near-you/>

This query bombs on me from query console
```select toGeometry(base64Decode('AQEAACDmEAAAT0wojs27YsA0a4TZX5hOQA==')) from meetupRsvp limit 10```
Am I using the function correctly here?
```org.apache.pinot.sql.parsers.SqlCompilationException: Caught exception while invoking method: public static byte[] org.apache.pinot.core.geospatial.transform.function.ScalarFunctions.toGeometry(byte[]) with arguments: [[B@f7f6884]```
