Error sending request too quick to npm

I'm trying to make create a mirror for about 2000 packages in npm. For each package, it fetches https://registry.npmjs.org/<package> and the downloads (https://api.npmjs.org/downloads/point/last-month/<package>) with Promise.all() But there is a few errors while fetching.

Error: connection error received: not a result of an error
        at mainFetch (ext:deno_fetch/26_fetch.js:182:43)
        at eventLoopTick (ext:core/01_core.js:164:35)
        at async fetch (ext:deno_fetch/26_fetch.js:392:7)

Maybe 2k requests in paralell is too much for Deno to handle? You could try to fetch 100 at a time Anyway, the error msg you're getting could be more clear

I already limited that only 30 requests can be made in 1 second.

fix(ext/fetch): retry some http/2 errors (#27417) · denoland/deno@b...

This brings some of the HTTP/2 retry behavior from reqwest to ext/fetch. It will retry very specific HTTP/2 errors once, if the body is able to be used again. Closes #27332
