I’m using the Python SDK to query my database using SQL. Using an API token with read/write access succeeds, but when using a read only token I receive a `FlightUnauthenticatedError` error. The query is a read only query. e.g. `SELECT * FROM my_table` ---

I tried again, and it appears to work now without any code change. Not sure what was causing the problem originally. Thank you.
