"The first argument must be one of type string or Buffer. Received type object", after clean wrangler generate of Scala worker

[asimpletune]

Hi, thanks for making this.

I tried this out after generating a clean wrangler project. After wrangler generate foo, I use miniflare index.js and navigating to the url in the browser I see:

The first argument must be one of type string or Buffer. Received type object

Hey! 👋 Are you able to share the full stack trace you're getting from the console?

Sure, here's what's being logged:

Ah ok. I just generated a new project from the template I'm guessing you're using and it's working for me. I think this might be the same issue as #35 though, since you're using Node 12.14. Would you be able to try with Node >= 12.19?

Sure, I'll give that a shot. Thanks for the fast response.

[asimpletune]

That did the trick. I guess the older APIs provided by the older version of node had different type expectations. Thanks!
