Cannot use import statement outside a module when using wrangler v2

Question

I'm new to using cloudflare and wrangler. I've a project that I've been working on, and I'm now trying to deploy it using wrangler publish, but I keep running into issues. My product is coded in node.js, and I'm using version 2 of wrangler. When I execute wrangler publish I get:

Basic JavaScript project found. Skipping unnecessary build!
Error: Something went wrong with the request to Cloudflare...
Uncaught SyntaxError: Cannot use import statement outside a module
  at worker.js:2Basic JavaScript project found. Skipping unnecessary build!
Error: Something went wrong with the request to Cloudflare...
Uncaught SyntaxError: Cannot use import statement outside a module
  at worker.js:2

I've searched for a solution, and one of them that I found said to change module in wrangler.toml from type="javascript"to type="webpack" however that gives me a bunch of errors:

 ./node_modules/destroy/index.js
Module not found: Error: Can't resolve 'fs' ... Parsed request is a module...resolve as module
      /Users/Desktop/APIs/cpiCalculator2/node_modules/destroy/node_modules doesn't exist or is not a directory
...
Error: webpack returned an error. You may be able to resolve this issue by running npm install.

I've tried reinstalling npm as it suggests and then wrangler publish again, but that just gives me the same error message.

I'm really not sure what the issue is, and I would really appreciate any help or advice on how to resolve this issue. Thank you!

Also, just a note, I'm not sure if this is affecting it, but I do have two other js documents in the main area of my project (where my index.js file is).
