Describe the Bug

Observed behavior

wrangler pages dev [directory] fails on v3.62.0. The exact same command is successful using v3.61.0 though.

Expected behavior

Successfully run the local server.

Steps to reproduce

• Initialize node project directory.
• Create test page in subdirectory. ex. site/index.html
• Create package.json script. "dev": "wrangler pages dev site"
• Install wrangler. ex. pnpm i -D wrangler or npm i -D wrangler
• Run package.json script. pnpm run dev or npm run dev (neither worked for me.)

I just tried to reproduce this on MacOS and Windows and it worked both times. For example on Windows:

PS C:\Users\Admin\dev\temp\foo> pnpm run dev

> [email protected] dev C:\Users\Admin\dev\temp\foo
> wrangler pages dev site

Could you create a reproduction and push it to a github repository so that we can try it out?

[Sammy-T]

Sure, I updated the description with a link to it.

@Sammy-T I'm unable to reproduce this with your reproduction repo. Could you try upgrading to the latest version of Node & Wrangler? What's the specific version number of your Windows 10 install?

[Sammy-T]

I updated both wrangler and node and it still fails. Here's my OS info and the received error.

Same for me [email protected] works but anything later breaks with the same error (windows 10 22h2) EDIT: Solved it thanks to https://github.com/cloudflare/workers-sdk/issues/6170#issuecomment-2245209918

That seems to have fixed it for me. Thanks, @cpakken.
