Wrangler dev dies on modifying imported text (css) file

loren.brichter · January 31, 2023, 3:19pm

Running wrangler dev like so: wrangler dev --local --local-protocol=https --persist Has always worked fine, but at some point in the last few wrangler updates whenever I modify a .css file (referenced in js via import it dies and I have to restart wrangler). I get this error:

[mf:err] Error: ENOENT: no such file or directory, open '/private/var/folders/0b/nkcg3qd51sj54_knx9ywmb580000gn/T/tmp-15615-nOOiiukcD1fN/3c9b9edaab109f0146e4a46ceeb13f73e6c60bd9-style.css'

I have to kill and restart the dev server to get it to serve the update. (As an aside, is there a way to have it cache and reuse the self-signed certs during local dev so you don’t have to constantly re-approve the cert (takes 3 clicks) when developing in Safari on every reload?

Tried updating to latest and tried with a fresh wrangler project, unfortunately still happening. Is there a better place to submit a bug report that people will see? Really kills the flow when working.

bug

### Which Cloudflare product(s) does this pertain to? Wrangler ### What versio…n of `Wrangler` are you using? 2.9.0 ### What operating system are you using? Mac ### Describe the Bug This seems like a new bug, this behavior used to work fine (last I checked it worked in 2.4.2). If I have `index.js` and `example.txt` `index.js`: ``` import example from './example.txt'; export default { async fetch(request, env, ctx) { return new Response(example); }, }; ``` `example.txt`: ``` this is a test ``` now I run `wrangler dev` in `local` mode, whenever I modify and save `example.txt` wrangler throws the following error: ``` [mf:err] Error: ENOENT: no such file or directory, open '/private/var/folders/0b/nkcg3qd51sj54_knx9ywmb580000gn/T/tmp-2506-ACQmyPnLTG9D/1ff2b3704aede04eecb51e50ca698efd50a1379b-example.txt' ``` I spelunked briefly in the tmp folders, and it looks like the cached file is not regenerated, but the wrangler dev server is looking for the file under a new hash name and (obviously) not finding it. Maybe a miniflare regression? This has been a real showstopper recently.
