Bug after upgrading to wrangler 3.28.1

After upgrading wrangler from 3.28.0 -> 3.28.1, I run into this: Error: Cannot find module 'worker/node_modules/miniflare/dist/src/index.js'. Please verify that the package.json has a valid "main" entry Manually checking that folder shows that the dist folder is missing. Upon downgrading to 3.28.0, it properly shows up again. Is this a known issue?

Hey! 👋 Thanks for reporting this, could you share the output of npm why miniflare after upgrading? Would you also be able to take a backup of your package lockfile (package-lock.json, yarn.lock, etc), delete it, then rerun the install command?

for reference, here is my npm why miniflare

➜  worker git:(main) ✗ npm why miniflare
[email protected] dev
node_modules/miniflare
  miniflare@"3.20240129.2" from [email protected]
  node_modules/wrangler
    dev wrangler@"^3.28.0" from the root project

➜  worker git:(main) ✗ npm why miniflare
[email protected] dev
node_modules/miniflare
  miniflare@"3.20240129.2" from [email protected]
  node_modules/wrangler
    dev wrangler@"^3.28.0" from the root project

I deleted my package locks & installed the latest 3.28.2 and I'm not getting the issue anymore. I do see that the miniflare dependency was bumped between 3.28.0 -> 3.28.2, so I'm not sure if it was that bump or clearing the old lockfiles that fixed it, but either way it's fixed now. Appreciate the response & thank you 🙏
