shard.broadcastEval gives me a reference error even tho all vars are defined

So I just sharded my bot and was playing around with client.broadcastEval and it gives me this. got a channelCreate.js event file like so:

module.exports = async (Discord, client, newChannel) => {
  let logC;
  console.log(newChannel.guild.name);
  client.shard.broadcastEval(
    async (c, { channelId }) => {
      logC = await c.channels.fetch(channelId);
      if (logC) {
        logC = logC;
        return true;
      }
    },
    { context: { channelId: "1061724696493703248" } }
  );
  logC.send("SHARD GOOD");
};

module.exports = async (Discord, client, newChannel) => {
  let logC;
  console.log(newChannel.guild.name);
  client.shard.broadcastEval(
    async (c, { channelId }) => {
      logC = await c.channels.fetch(channelId);
      if (logC) {
        logC = logC;
        return true;
      }
    },
    { context: { channelId: "1061724696493703248" } }
  );
  logC.send("SHARD GOOD");
};

and it gives this error when a channel is created

node:internal/process/promises:246
          triggerUncaughtException(err, true /* fromPromise */);
          ^

but it logs the guild name before crashing... also after the bot crashes it restarts itself automatically and thats weird cuz i dont have no such thing set up

but it happens only during that event and i have only one channelCreate listener do u need my shard.js file ? i dont understand sorry... how do i do a project wide search vs code ctrl + f ??

wenOP•2y ago

@qjuh sorry i slept

wenOP•2y ago

well this is my event handler

wenOP•2y ago

yes i save after every line 💀 ok so the error is not arising from the event file

wenOP•2y ago

wenOP•2y ago

that is the error it throws after logging the whole client object for some reason and then runs the bot again with the main file (index.js)

wenOP•2y ago

it appears to be arising from here

so i use the context object to pass in more properties that i need? like channelId or reply and stuff for example ? that actually makes total sense tysm!! oh btw... if i like define something outside the function... like let me = "bot" will it be accessible or do i need to { context: { text: me } } alright ty !!

wenOP•2y ago

it works if i do this... but I cant pass in the whole message object ?

oh... so i need to import the class directly inside the function but like... i was able to pass message.author but not message

ouu got it so i can just use the usual code... but in any case suppose i need to fetch the channel using id... then i'll have to use broadcastEval right ??
