(CaseClauseError) no case clause matching: :ok

[daniloraisi]

I am using SRH to test locally an implementation using Upstash Redis, but I can't make it work.

A brief context: I'm running a serverless function on Supabase Edge Functions (this is working locally using Docker).

The code is written in Typescript using Deno. I omitted some code for simplicity.

Deno.serve(async (_req) => {
  const redis = new Redis({
    url: Deno.env.get("UPSTASH_REDIS_REST_URL"),
    token: Deno.env.get("UPSTASH_REDIS_REST_TOKEN"),
  });

  // (...) omitted code

  for (const mention of mentions) {
    const exists = await redis.exists(mention.cid);
    
    if (exists) {
      continue;
    }
    
    // (...) omitted code

    await redis.set(target.cid, "reposted");
  }

  return new Response({ message: "Processing done" }, {
    headers: { "Content-Type": "application/json" },
  });
});

My docker-compose.yml is configured like the instructions on the README.

services:
  redis:
    image: redis:latest
    ports:
      - "6379:6379"
  serverless-redis-http:
    ports:
      - "8079:80"
    image: hiett/serverless-redis-http:latest
    env_file: .env
    environment:
      SRH_MODE: env
      SRH_TOKEN: ${UPSTASH_REDIS_REST_TOKEN}
      SRH_CONNECTION_STRIN: redis://redis:6379

When trying to connect using the Redis client, I'm getting this Elixir error on SRH Container

A note about the log: it is pointing to host.docker.internal because my Serverless Function is running on a separated network.

Any thoughts?

Hm, interesting that it's hitting the /pipeline endpoint, but your commands are directly with the client. Do you have automatic pipelining turned on? Is there a way to turn that off on the upstash client?
I will investigate further, but that might be a starting point to see if it's something to do with that (and may not be an issue on the normal endpoint, or if is, will provide further clarity)

@hiett I tried your suggestion.

When creating my Redis client I set the pipeline to false, but I am still facing the same issue.

const redis = Redis.fromEnv({
  enableAutoPipelining: false,
});

The project is up and running on production, and working correctly with the prod Upstash Redis.
