> Trying to index into a non-array yields an AssertionError (with no error
> message other than a type name) rather that a message referring to the
> problem (e.g., that an array indexing operation was applied to an expression
> whose type turned out to be a non-array type):
> {noformat}
> 0: jdbc:drill:zk=local> SELECT catalog_name[1] FROM
> INFORMATION_SCHEMA.CATALOGS;
