Description

Since 4.1.0, cqlsh fails on COPY commands with standard output as target.

Steps to reproduce:

$> docker run -d --name cassandra --rm cassandra:4.1.1
$> docker exec cassandra cqlsh -e 'COPY system.local(cluster_name) TO STDOUT'
  <stdin>:1:'NoneType' object is not callable

Possibly a regression introduced by this commit 6341319.

Also, it looks like it has happened before: CASSANDRA-12497
