No clue. Workers are more up-to-date and powerful though.

Iixixix I think you can bind it directly within that same worker and access it via `env`...

Hey

I am trying to call a DO from Worker B when DO is exported from worker A.
Worker A looks like this:

# wrangler.toml B
name = "worker-B"
# ...
[env.dev.durable_objects]
bindings = [
  { name = "DO", class_name = "Do", script_name="worker-A" }
]

# wrangler.toml B
name = "worker-B"
# ...
[env.dev.durable_objects]
bindings = [
  { name = "DO", class_name = "Do", script_name="worker-A" }
]

# wrangler.toml B
name = "worker-B"
# ...
[env.dev.durable_objects]
bindings = [
  { name = "DO", class_name = "Do", script_name="worker-A" }
]

# wrangler.toml B
name = "worker-B"
# ...
[env.dev.durable_objects]
bindings = [
  { name = "DO", class_name = "Do", script_name="worker-A" }
]

# wrangler.toml A
name = "worker-A"
# ...
[env.dev.durable_objects]
bindings = [
  { name = "DO", class_name = "Do" }
]

[[migrations]]
tag = "v1"
new_sqlite_classes = ["Do"]

# wrangler.toml A
name = "worker-A"
# ...
[env.dev.durable_objects]
bindings = [
  { name = "DO", class_name = "Do" }
]

[[migrations]]
tag = "v1"
new_sqlite_classes = ["Do"]

# wrangler.toml A
name = "worker-A"
# ...
[env.dev.durable_objects]
bindings = [
  { name = "DO", class_name = "Do" }
]

[[migrations]]
tag = "v1"
new_sqlite_classes = ["Do"]

# wrangler.toml A
name = "worker-A"
# ...
[env.dev.durable_objects]
bindings = [
  { name = "DO", class_name = "Do" }
]

[[migrations]]
tag = "v1"
new_sqlite_classes = ["Do"]

And the index.ts in worker B is a fetch calling a DO stub (with RPC), and exporting the fetch.
On Worker A, it's a simple fetch + DO sqlite, both exported.

Worker A deploys fine and works fine with DO. I get this error on deploy for worker B (that should use the DO from worker A):

Cannot create binding for class in script 'worker-A' that does not exist [code: 10061]

Cannot create binding for class in script 'worker-A' that does not exist [code: 10061]

Cannot create binding for class in script 'worker-A' that does not exist [code: 10061]

Any idea what I could be doing wrong?

my plan is when someone clicks something from my CF pages site, it creates a D1 database and we need to bind that to 3 CF workers. It doesn't have to be instant but quick enough that it's not waiting 5 - 10 minutes

Sxyzo•10/31/24, 2:33 AM

Hi! I'm trying to get two Workers to communicate using RPC, but it's not working when I try to use a named export.

When I try to call

methodX()

methodX()

methodX()

methodX(), I get this error:

The RPC receiver does not implement the method "methodX"

The RPC receiver does not implement the method "methodX"

The RPC receiver does not implement the method "methodX"

The RPC receiver does not implement the method "methodX"

Here's my setup that's NOT working:

In Worker A's config file (wrangler.toml), I have:

compatibility_date = "2024-10-22"
[[env.staging.services]]
binding = "STORAGE_SERVICE"
service = "storage_service"
entrypoint = "StorageService"

compatibility_date = "2024-10-22"
[[env.staging.services]]
binding = "STORAGE_SERVICE"
service = "storage_service"
entrypoint = "StorageService"

compatibility_date = "2024-10-22"
[[env.staging.services]]
binding = "STORAGE_SERVICE"
service = "storage_service"
entrypoint = "StorageService"

compatibility_date = "2024-10-22"
[[env.staging.services]]
binding = "STORAGE_SERVICE"
service = "storage_service"
entrypoint = "StorageService"

And in Worker B, I'm doing:

export class StorageService extends WorkerEntrypoint<Bindings> {
    async methodX() {
        // stuff happens here
    }
}
export default {
    async fetch() {
        return new Response("Hello world");
    }
}

export class StorageService extends WorkerEntrypoint<Bindings> {
    async methodX() {
        // stuff happens here
    }
}
export default {
    async fetch() {
        return new Response("Hello world");
    }
}

export class StorageService extends WorkerEntrypoint<Bindings> {
    async methodX() {
        // stuff happens here
    }
}
export default {
    async fetch() {
        return new Response("Hello world");
    }
}

export class StorageService extends WorkerEntrypoint<Bindings> {
    async methodX() {
        // stuff happens here
    }
}
export default {
    async fetch() {
        return new Response("Hello world");
    }
}

But here's the weird part

if I remove the named entrypoint stuff and just do it like this, it works perfectly:

compatibility_date = "2024-10-22"
[[env.staging.services]]
binding = "STORAGE_SERVICE"
service = "storage_service"

compatibility_date = "2024-10-22"
[[env.staging.services]]
binding = "STORAGE_SERVICE"
service = "storage_service"

compatibility_date = "2024-10-22"
[[env.staging.services]]
binding = "STORAGE_SERVICE"
service = "storage_service"

compatibility_date = "2024-10-22"
[[env.staging.services]]
binding = "STORAGE_SERVICE"
service = "storage_service"

ith Worker B simplified to:

export default class StorageService extends WorkerEntrypoint<Bindings> {
    async methodX() {
        // stuff happens here
    }
}

export default class StorageService extends WorkerEntrypoint<Bindings> {
    async methodX() {
        // stuff happens here
    }
}

export default class StorageService extends WorkerEntrypoint<Bindings> {
    async methodX() {
        // stuff happens here
    }
}

export default class StorageService extends WorkerEntrypoint<Bindings> {
    async methodX() {
        // stuff happens here
    }
}

Any ideas what I might be doing wrong with the named export version? I kind of need to keep that structure for other parts of my app.

Thanks in advance!

You need to specify the named entrypoint in your Wrangler.toml.

Those are probably shell commands. On macOS/Linux you run them in a Terminal, on Windows the easiest way is probably to use WSL https://learn.microsoft.com/en-us/windows/wsl/
