I am trying to use the dremio_client command to issue a SQL command to the Dremio server. However, I am getting a client side certificate verification error even when I use the --skip-verify argument
First, I installed dremio-client using the pip3 command like this:
$ pip3 install dremio-client
Then I attempted to run the following command:
$ dremio_client --ssl --skip-verify --hostname dremio.org --port 443 --username <MY USERID> --password '<MY PASSWORD>' query --sql 'select * from sys.options'

I also tried placing the configuration in the file: ~/.config/dremio_client/config.yaml but I experienced the same error.
