Note that some of the linting doesn't really apply here, based on the execution environment of mongo-init.js (ex: sleep() is very much a thing). As the wiki mentions, other tests don't reliably run in Docker, so I'd be happy to review the results here (perhaps tackling that in a separate issue).

It occurs to me that as a first-time contributor, an admin would need to approve running the workflows here. If one wouldn't mind kicking things off (with the above caveats), I'd be happy to help close this out!

As mentioned above, this code runs in Mongo's execution context. rs and sleep are very much defined. This leaves:

Error: 5:1 error Expected an assignment or function call and instead saw an expression no-unused-expressions

If the expression conditional syntax is an issue here, happy to change it, but before I do I'd appreciate confirmation from a maintainer that we can either suppress or ignore the other linting here.

Looking forward to getting this merged!

We're now using Mongo version 5.0.23, so I'm closing this. If you're still having a problem, please open a new issue. Thanks!
