Have a TSV file. I am able to do a select * and select columns[0] etc from the tsv file just
fine.

However if I specify an invalid column the query just hangs sqlline- Should fail with an error.

The logs contain an error message like this
Exception in thread "dca6a192-a774-4389-b03e-55ad21745ebd:frag:0:0" java.lang.IllegalArgumentException:
Selected column must have name 'columns'
