service binding error.. why?

any ideas why i get this Error:

 errorTypeError: The RPC receiver does not implement the method "textLableMatch".

 errorTypeError: The RPC receiver does not implement the method "textLableMatch".

worker A "consumer":

export default {

    async fetch(request, env, ctx) {
        try {
            const lables = ['stuff', 'bla', 'box'];
            const text = 'blablablalballb!';
    
            const result = await env.WORKER_TEXT_LABLE_MATCH.textLableMatch(lables, text);
            return new Response(JSON.stringify(result));
            
        } catch (error) {
            return new Response("error" + error, { status: 500 });
        }

    },
};

export default {

    async fetch(request, env, ctx) {
        try {
            const lables = ['stuff', 'bla', 'box'];
            const text = 'blablablalballb!';
    
            const result = await env.WORKER_TEXT_LABLE_MATCH.textLableMatch(lables, text);
            return new Response(JSON.stringify(result));
            
        } catch (error) {
            return new Response("error" + error, { status: 500 });
        }

    },
};

Worker B "producer":

export class LableMatch extends WorkerEntrypoint {
    async textLableMatch(lables, text) {
            console.log('Running ai mathing');
            console.log('lables:' + lables + 'text:' + text);
            const result = await this.aiMatching(lables, text);
            return result;
    }
}

export class LableMatch extends WorkerEntrypoint {
    async textLableMatch(lables, text) {
            console.log('Running ai mathing');
            console.log('lables:' + lables + 'text:' + text);
            const result = await this.aiMatching(lables, text);
            return result;
    }
}

Can you share your toml? How is your service binding defined in there? (Also note that your entrypoint for the producer must be in the main file)

Corsix👾OP•3mo ago

TOML file for consumer worker : #:schema node_modules/wrangler/config-schema.json name = "image-picker" main = "src/index.js" compatibility_date = "2024-09-09" compatibility_flags = ["nodejs_compat"] services = [ { binding = "WORKER_TEXT_LABLE_MATCH", service = "ai-text-label-match" } ] worker B producer code is in the main index file

You'll want

services = [
  { binding = "WORKER_TEXT_LABLE_MATCH", service = "ai-text-label-match", entrypoint = "LableMatch" }
]

services = [
  { binding = "WORKER_TEXT_LABLE_MATCH", service = "ai-text-label-match", entrypoint = "LableMatch" }
]

see https://developers.cloudflare.com/workers/runtime-apis/bindings/service-bindings/rpc/#named-entrypoints for more

oh okey, wasent shown in the example on that page so had no idea to add entrypoint = "LableMatch"
