Cannot find module 'ws'

[AustinMutschler]

In the past day or so we noticed that our docker containers were no longer running correctly. When we looked at the error we saw this. They were working 3 days ago but not anymore. We have tried to re-build older code from a week or two ago that we knew worked and it also gave this same error message.

We were able to recreate locally as well.

Node 14
Socket Redis Adapter 7.x

We also noticed this warning while installing the packages:

#15 112.2 warning "@socket.io/redis-adapter > [email protected]" has unmet peer dependency "ws@*".
