y'know I gotta say,

AssertionError [ERR_ASSERTION]: The expression evaluated to a falsy value:

AssertionError [ERR_ASSERTION]: The expression evaluated to a falsy value:

is the most obnoxious, frustrating type of error I've ever seen. This is so unhelpful to the point of making me want to flip a table.

The whole stack trace below just points to the miniflare lib, not my own code, so I have no idea what ever causes this, I have to fumble in the dark like a caveman using ECMAScript 1 in 1998

<Alterion.Dev>OP•1/10/24, 3:12 AM

I have an older version of the worker lib, so does it come from elsewhere?

<Alterion.Dev>OP•1/10/24, 3:13 AM

Can't wait for this to be fixed either way this is really aggravating and I don't like the feeling of frustration that comes with it

James•1/10/24, 3:13 AM

How old? This was introduced a couple months ago I think

<Alterion.Dev>OP•1/10/24, 3:13 AM

3.0.0 I think

James•1/10/24, 3:13 AM

You can grab the pre-release in that PR if you want to give it a try

<Alterion.Dev>OP•1/10/24, 3:14 AM

I rolled back after trying to update from a warning lol

<Alterion.Dev>OP•1/10/24, 3:14 AM

I'll try the PR, that might at least hold me off until the fix

James•1/10/24, 3:14 AM

3.0.0 is very very old, I would definitely not recommend a version that old

<Alterion.Dev>OP•1/10/24, 3:14 AM

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

from the early days, but yes - here is a release notes that references it: https://community.cloudflare.com/t/2018-11-29-workers-runtime-release-notes/47396

schwartzmj•1/10/24, 4:46 PM

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

e.g.

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.

kian•1/10/24, 4:47 PM

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

kian•1/10/24, 4:47 PM

All metrics in the dash are just GraphQL or API calls that you can make yourself

Good idea

ottermanempire•1/10/24, 6:18 PM

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

Hi, how do i get access to browser workers, currently getting the following error

workers.api.error.no_access_to_browser_worker [code: 10088]

Aalfl I'm removing a bunch of bindings -- what should I do with the data?

Chaika•1/10/24, 7:54 PM

No way to delete, all data is deleted after 93 days though, at which point the dataset will be gone too

Erisa•1/10/24, 8:11 PM

I'd probably email security@cloudflare.com for a request like that

Though if you already have a support ticket that's fine too, we can take it from there

Hey, just curious if its possible to setup a Cloudflare Worker that only handles CORS policies and use that Worker in all the other Cloudflare Worker scripts that need CORS policy implementation? - I don't understand CORS fully so, if this is not possible just let me know, thank you

Al Hill•1/11/24, 9:35 AM

Is there any way to know at execution time how much subrequests has done a worker? I'm reaching the limit and I'd like to know it to have unless one extra subrequest available to write in db the progress done at first attempt

Hi, does anyone know how to get the r2 endpoint when running the worker locally? I need that for using pre-signed urls in local environment.

kian•1/11/24, 2:20 PM

Local development doesn’t emulate the S3 API so there is no endpoint, you’d need to hit the production/live one

Isaac McFadyen•1/11/24, 2:31 PM

The subrequest limit should be documented based on the plan the Worker is on, if that's what you mean?

Isaac McFadyen•1/11/24, 2:31 PM

https://developers.cloudflare.com/workers/platform/limits/

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

Al Hill•1/11/24, 7:04 PM

so I could stop the loop, save a bookmark in the database, and "paginate" the work

kian•1/11/24, 7:06 PM

Workers don’t expose that so your only option would be implementing your own counter

i want to send a csv or pdf to a cloudflare worker via a multipart/form-data post method. I then want to parse the file and do something with the result

kian•1/12/24, 12:02 AM

await request.formData() -> https://developer.mozilla.org/en-US/docs/Web/API/FormData

MDN Web Docs

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".

Socal•1/12/24, 12:13 AM

ok, i can see the formData() response, but it doesn't have a get() method on it
