Does

getPlatformProxy

getPlatformProxy

not support RPCs?

I'm trying to access RPCs from a worker in a pages project, and I'm using

getPlatformProxy

getPlatformProxy

to access the cloudflare env in local development.

However, when trying to call an RPC on a bound service, I get the following error:

If I call the RPC from a regular workers project it works just fine.

Jakob Norlin•7/18/24, 12:08 PM

The above error is from this code snippet

const { getPlatformProxy } = await import("wrangler")
const platform = await getPlatformProxy()
console.log(await platform.env.MY_SERVICE.testRPCFunction())

const { getPlatformProxy } = await import("wrangler")
const platform = await getPlatformProxy()
console.log(await platform.env.MY_SERVICE.testRPCFunction())

const { getPlatformProxy } = await import("wrangler")
const platform = await getPlatformProxy()

Dario•7/18/24, 1:51 PM

getPlatformProxy

getPlatformProxy

should definitely support RPC: https://github.com/cloudflare/workers-sdk/blob/e7c06d78b14eb89060f431bc4aee8dbc1cc08fa5/fixtures/get-platform-proxy/tests/get-platform-proxy.env.test.ts#L182

I think this is blowing up in the Miniflare magic proxy as the code is trying to send some non serializable object across the wire (the error message comes from devalue which the magic proxy uses to serialize values: https://github.com/Rich-Harris/devalue/blob/0c35c0e7a6a37172c7f049eaae4e7079559ba250/src/stringify.js#L149)

hi i'm trying to automate the syncing of my secrets so biasing towards using wrangler for managing them.. the CLI is showing secrets but I don't see them in the dashboard and my app also isn't getting them in context.

✗ wrangler secret list -c wrangler.toml
[
  {
    "name": "CF_ACCESS_KEY_ID",
    "type": "secret_text"
  },

✗ wrangler secret list -c wrangler.toml
[
  {
    "name": "CF_ACCESS_KEY_ID",
    "type": "secret_text"
  },

✗ wrangler secret list -c wrangler.toml
[
  {
    "name": "CF_ACCESS_KEY_ID",
    "type": "secret_text"
  },

✗ wrangler secret list -c wrangler.toml
[
  {
    "name": "CF_ACCESS_KEY_ID",
    "type": "secret_text"
  },

one thing I noticed is that

-e foo

-e foo

seemingly makes no difference, list returns results irrespective of the environment i specify. Am I missing something obvious?

Hey everyone, I am trying to setup jest unit testing for my functions. I have my example dir set up like this:
functions/
functions/user.ts
functions/user.test.ts

This works fine in the fact that I can run the jest tests and I can also run wrangler. But Wrangler constantly complains (See screenshot). Why are these even popping up when I am trying to run my page/functions. How do I exclude them so they do not show up while I am running locally?

Is there a way to get the environment information on which worker is being deployed on in custom builds?
What I mean is, I have a script which runs before deployement and does some stuff, but it needs to know the environment
Which I pass to wrangler as

wrangler deploy --env prod
I looked to env variables but I dont think wrangler relays this to custom build script

NVM build is not top-level only directive so i just placed it under [env.prod]

I want to create a custom domain with a wildcard, something like

]

routes = [

Which fails with:

✘ [ERROR] Cannot use "*.wix-app-test2.run/*" as a Custom Domain; wildcard operators (*) are not allowed

Now, I know that this is possible from withing the Dashboard (we have such a custom domain). This means that we cannot use our Wrangler integration, because it will eigther fail, or remove the wildcard setup (if I don't have it in my wrangler config).
Is there a solution for that?
