Require non-empty column list. #371

Closed sentry-io[bot] closed 3 years ago

sentry-io[bot] commented 4 years ago

We don't check the length of the column list before attempting an exploration. This results in the below exception because an implicit assumption is that there is at least one column.

Solution: validate the list length at the api boundary.
