You should be bubbling errors up to some top level and at least catching them there.

Wrapping entire async-fn bodies with try/catch (or outright overuse of try/catch) is probably the most ubiquitous beginner mistake I see in modern Javascript.

For example, imagine if your top level was even just run().catch(console.error).
