I get similar results on https://github.com/taskcluster/docker-exec-websocket-server - the test docker exec wc -c passes on Node.js 14.17.15 but fails on 16.13.2. And, there are pending updates, including bumping ws from 7.1.2 to 7.4.6.

Fixed with the taskcluster/docker-exec-websocket-server update and PR #2.
