Best place for an official answer would be an account ticket with support. I don’t think there’s anything wrong with doing it given you have permission

I gave this a shot. It's a bit complicated but from what I can see, the workers endpoint you referenced is specifically for workers. I found an endpoint for "pages", but i'm unable to get the name of the pages project in the results. I instead get back a randomized

scriptName

scriptName

scriptName

scriptName e.g.

pages-worker--123456-production

pages-worker--123456-production

pages-worker--123456-production

pages-worker--123456-production for each invocation.

Any insight on this? Are there any other solutions? I find it bizarre that I can't get a breakdown of usage per project (without going into 50+ project dashboards manually). Hopefully Cloudflare is working on some improvements to that.

Look at the GraphQL calls that the individual project dashboards are making

Sorry for the dumb question, is it possible to use

await cache.match()

await cache.match() within a worker to pull a json file within a private R2 that I would otherwise access with the original

await env.bucket.get()

await env.bucket.get() method? Wondering because it won't have a url to build the cacheKey

Al Hill•1/11/24, 7:03 PM

I saw the limits, the problem is the function i'm developing need more or less subrequests depending on different things... so it would be useful knowing when it's going to crash into a "Error: Too many subrequests" loophole

FormData - Web APIs | MDN

The FormData interface provides a way to construct a set of key/value pairs representing form fields and their values, which can be sent using the fetch(), XMLHttpRequest.send() or navigator.sendBeacon() methods. It uses the same format a form would use if the encoding type were set to "multipart/form-data".

requests that

return new Response(null, {
