Describe the Bug

Observed behavior

Expected behavior

Expect to be able to view content, even when wrangler.toml exists.

Steps to reproduce

  1. pnpm add -D wrangler@3.62.0
  2. echo hello > index.html
  3. pnpm wrangler pages dev .
  4. Command-click the URL in the console and see "hello" in the default browser
  5. [ctrl]+[c] to end the wrangler process
  6. echo 'name = "foo"' > wrangler.toml
  7. pnpm wrangler pages dev .
  8. Command-click the URL in the console and see that the default browser fails to return the page

Please provide a link to a minimal reproduction

Actually, this could be a misunderstanding on my part...

The Pages docs do indicate that wrangler configuration is for Functions and that "Configuration via wrangler.toml is in open beta."

That said, when I first ran into this problem, I was specifying a port in wrangler.toml, which was being applied successfully in a wrangler pages dev command. It also logged "No functions. Shimming..."

Is the observed behaviour unexpected so far as the team's concerned?

scruffymongrel commented 3 months ago

I mentioned this issue in the #functions channel on Discord and was asked whether using a subdirectory might help.

After checking, it appeared to still be a problem... in trying to get to Discord, I fumbled switching apps and landed in my browser, which was showing the expected content! When I checked the console, I saw a message similar to the following:

This output is the result of pnpm wrangler pages dev . and seems to have resolved quicker than others (~6 seconds, whereas most have taken 10-12ish seconds).

Turns out I just needed to ps aux | grep wrangler to find the spare wrangler processes running on non-standard ports and kill them off. Problem solved.

Thanks, I also had this issue and turns out there was another wrangler process. I got error messages that was also shown in https://github.com/cloudflare/workers-sdk/issues/4562.

For SEO for other users, error looked like:
