Folks, I tried upgrading node from 16.19.1 to 18.16.1. With 16.19.1 & wrangler 3.1.2 everything works. But when I try node 18.16.1 I get:

Note there is no wrangler.toml .. I've basically created the simplest repo that produces the bug

H

hanpolo•7/7/23, 9:47 PM

Ok .. so verified what you said, @cherryjimbo. If I run

node --dns-result-order=ipv4first node_modules/wrangler/bin/wrangler.js pages dev -- npm start

node --dns-result-order=ipv4first node_modules/wrangler/bin/wrangler.js pages dev -- npm start

node --dns-result-order=ipv4first node_modules/wrangler/bin/wrangler.js pages dev -- npm start

node --dns-result-order=ipv4first node_modules/wrangler/bin/wrangler.js pages dev -- npm start

Then everything works

H

hanpolo•7/7/23, 9:48 PM

not quite sure how else to pass node command line arguments (i.e. --dns-result-order) to npx .. so I'm stuck with this rather long-winded node command. Any suggestions?

Does Miniflare 3 have any mechanism to overwrite what domain names map to (within the API, not wrangler)? For example, if my worker is doing a fetch to

https://my.custom.domain.com

https://my.custom.domain.com

https://my.custom.domain.com

https://my.custom.domain.com, I would like that to get routed to a localhost server for CI testing purposes without changing the URL within the code.

My tests using

unstable_dev() and R2 fail in CI. Has anyone seen something similar? Sadly giving a longer timeout (5+sec) for the test doesn't seem to fix the problem. The test finishes in local in 24ms.

I ended up doing this: ```js export default { async fetch(request, env) { process.env =
