what GRPC code are you returning?

set grpc-status header to PERMISSION_DENIED but didn't change anything

are you using some sort of GRPC gateway?

Have a wasm plugin that for eg. will return 401 if no api key is present

liam | helius.devOP•11/13/23, 5:14 PM

for http1 this works, for grpc the LB returns 520

Lliam | helius.dev Have a wasm plugin that for eg. will return 401 if no api key is present

CB•11/13/23, 5:15 PM

What that sounds like to me is the gateway you are using is translating the GRPC -> to http1 error codes incorrectly

CB•11/13/23, 5:15 PM

when the grpc request is authenticated does it work correctly?

CCB when the grpc request is authenticated does it work correctly?

liam | helius.devOP•11/13/23, 5:16 PM

So to use Pages advanced mode I have to use this https://developers.cloudflare.com/pages/platform/functions/advanced-mode/

I did follow the docs, but like im struggling with putting the _worker.js in the actual output dir??

Like as you can see in the first photo, running the build command generates a _worker.js file, but it is not the one that I wrote, how do I get MY worker to be in the build directory? Keep in mind I'm using svelte

Panda•11/13/23, 7:20 PM

This is my wrangler.toml file, it is worth noting that my worker is located in /worker/index.js

Erisa•11/13/23, 8:04 PM

If you switch your Worker to the new Standard pricing (or even the old Unbound pricing), the subrequest limit will be 1000 instead of 50

Isaac McFadyen•11/14/23, 12:35 AM

SvelteKit uses their own _worker.js, what is your purpose for using _worker.js? Also we should probably be talking in #functions

I am using Remix deployed on Pages, but since it's SSR, I hear that this is actually running on workers

ftqo•11/14/23, 12:39 AM

my issue is that i want the cookies sent to remix to be sent to another server

ftqo•11/14/23, 12:39 AM

is there any way to make this work?

ftqo•11/14/23, 12:49 AM

yeah im kinda lost, i assumed using remix for the frontend would work and allow me to fetch from an api and send the whole response back, but the api requires the user to be logged in

I was told by multiple people that I could run langchain with Cloudflare workers & wrangler

Am I being led in the wrong direction?

The issue I’m having is that I want to run langchain in a react native mobile application but the Hermes engine does not use “readable streams” which is how langchain responds
