Info needed: BadResource: Bad resource ID

[reselbob]

Hi:

I run this code and it does indeed consume and report published messages.

      (async function () {
        try{
          for await (const { channel, message } of sub.receive()) {
            handler(message);
          }
        }catch(err){
          console.log(err);
        }

But, I get an error BadResource: Bad resource ID.

Any idea what this means. I will very much appreciate the help.

Thanks in advance.

@keroxp I hope you don't mind me giving input...

@reselbob Can you provide the exact code you used? How you are running/using it? I assume the above is pseudo-code as well as it isn't valid code.

Usually I see Bad Resource ID when a subprocess using Deno.run isn't closed properly or passed invalid values

Here is the code: https://github.com/reselbob/denodemo/blob/master/pubbersubber/types/providers/redis.ts

Here is the project it runs within: https://github.com/reselbob/denodemo/tree/master/pubbersubber

Here is the test: https://github.com/reselbob/denodemo/blob/master/pubbersubber/tests/connection_test.ts , starting at line 63:

You need to have rabbitmq and redis running. I've put this all in the test script found here:

Thanks for your attention. Any help will be appreciated a lot! If the error is due some bad programming on my part, which it very well might be, please forgive me.

@reselbob Doesn't seem like any of those links work?

[reselbob]

Sorry, the repo was private. Now it's not.

[ebebbington]

No problem! Do you have the error stack it displays too?

@reselbob @ebebbington
Thanks for reporting this issue!
I was able to reproduce the same error.
I'll look into it.

Steps to reproduce

I have a file named mod.ts:

import { connect } from "https://deno.land/x/redis@v0.10.2/redis.ts";

const redis = await connect({ hostname: "localhost" });
const sub = await redis.subscribe("test");

(async () => {
  for await (const { channel, message } of sub.receive()) {
    console.log("channel: " + channel);
    console.log("message: " + message);
  }
})();

redis.close();

When running the mod.ts, the following error occurs:

$ deno run --allow-net ./mod.ts

@reselbob Hi! This problem has been fixed at v0.10.3. Please update to it.

@ebebbington Thanks for your help! It really helps us.

[ebebbington]

@uki00a Shame I didn't have the time to help out more!

[reselbob]

I am happy I was able to help. Deno is important as is being able to use Redis with it! Thanks for your attention.
