Review Comment:
Yea it can throw other `ValueError`s. And here is what it looks like in
console:
```
pyspark.errors.exceptions.connect.SparkConnectException: [NO_ACTIVE_SESSION]
No active Spark session found. Please create a new Spark session before running
the code.
```
To verify this, I manually changed the code to throw a ValueError. Is there
a way to trigger other GRPC Cannot invoke RPC errors?
