I'm currently in the process of trying to register my slash commands across 10 shards for my bot, and in doing so I'm coming accross this error:

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

Error [SHARDING_IN_PROCESS]: Shards are still being spawned.

I'm not entirely sure what to do / how to go about fixing this issue.

This is how I'm trying to register my slash commands across each shard, I've tried doing it during a 'ready' event, and also the shardReady event from DJs but still no luck unfortunately.

bot.on('shardReady', async ()=> {
        (await PG(`${process.cwd()}/commands/*/*.js`)).map(async (file)=>{
            const cmds = require(file)
            await bot.shard.broadcastEval((c)=>{
                c.guilds.cache.forEach((guild)=>{
                    guild.commands.set(cmds).catch(()=>{})
                });
            });
        
        
        });

    });

and I'm currently handling my sharding with:

const { ShardingManager } = require('discord.js');
const { token, dblToken } = require('./config.json');
const manager = new ShardingManager('./bot.js', {
  token,
  totalShards: 11,
  respawn: true,
});
//const { AutoPoster } = require('topgg-autoposter')
 //const ap = AutoPoster(dblToken, manager)

manager.on("shardCreate", shard => {
  shard.on('reconnecting', () => {
    console.log(`Reconnecting shard: [${shard.id}]`);
  });
  shard.on('spawn', () => {
    console.log(`Spawned shard: [${shard.id}]`);
  });
  shard.on('ready', () => {
    console.log(` Shard [${shard.id}] is ready`);
  });
  shard.on('death', () => {
    console.log(`Died shard: [${shard.id}]`);
  });
});

 /*ap.on('posted', () => {
  console.log('Posted Stats.')
})*/ 

manager.spawn();

Any help would honestly be appreciated! I've been stuck with this for the last week and a half and my bot has been down since.
