Question

I'm getting this error:

[BITFIELD_INVALID]: Invalid bitfield flag or number: undefined

Code:

const client = new Client({ 
intents: [Intents.FLAGS.GUILDS, Intents.FLAGS.GUILD_MESSAGES, Intents.GUILD_VOICE_STATES] 
});

Answer from Zsolt Meszaros

It should be Intents.FLAGS.GUILD_VOICE_STATES instead of Intents.GUILDS_VOICE_STATE.

You can also set Intents via strings instead of Intents.FLAGS object.

const client = new Client({ 
  intents: ["GUILDS", "GUILD_MESSAGES", "GUILD_VOICE_STATES"] 
});
