[Pages/Functions] It works on my machine© but not in production

[kael]

I'm a happy Cloudflare user having fun with Workers, Pages and Functions.

Except I have a project that does not work in production.

I've started to debug using wrangler pages deployment tail and identified some causes.

Is it normal that it doesn't work identically in both environments ?

I tried to use the wrangler pages dev --local=false option but it doesn't seem to work:

wrangler pages dev --local=false --compatibility-date=2023-07-04 --ip '127.0.0.1' --port 3001 -- npm start"
...
Ready on http://127.0.0.1:3001/

My app queries Cloudflare DOH resolver https://1.1.1.1/dns-query?name=_mysrv&type=SRV and it would seem that depending if they are made locally or remotely the result is not the same (unclear). I've also cached DOH responses to reduce queries and avoid being hypothetically blocked, but get the same result.

How can I run the development code remotely for Pages ?

(Using ⛅️ wrangler 0.0.0-e16d0272).

I've identified the cause of the problem, the worker sends too many subrequests: Too many subrequests is returned.

How to run an environment locally identical to the production one (including all limits) ?
