"message.content" doesn't work in DMs - Discord.js - discord

Question

I tried to make a ping command for a DM channel, so if an author says ping in a DM channel, a bot could reply pong, but it’s not working. The console is not giving any error and the bot is not providing any output.
message.content doesn’t work in DMs.
client.on('messageCreate', (message) => {
if(message.author.bot) return
//command
if (message.content.toLowerCase() === `ping`) {
message.author.send(`pong`);
}
});

Answer 1

While the coco bar's answer is something that needs to be done, it may not be the full answer to the problems you are having. Something else you will want to make sure that you have enabled in the bot code is your intents. Somewhere in your code you have a line that starts off like this (may not be exactly this):
const client = new Client({})
Make sure you have your intents enabled there.
Example 1 enables minimum intents:
const client = new Client({
intents: ['GUILDS', 'GUILD_MEMBERS', 'GUILD_MESSAGES', 'DIRECT_MESSAGES'],
})
Example 2 enables all intents:
const client = new Client({
intents: 131071,
})
Example 3 enables all intents with partials:
const client = new Client({
intents: 131071,
partials: ['CHANNEL', 'GUILD_MEMBER', 'GUILD_SCHEDULED_EVENT', 'MESSAGE', 'REACTION', 'USER']
})
UPDATE intents: 32767 no longer includes all intents; all intents are now 131071

Answer 2

message.author doesn't have any content property. If you want to check the message content, use MessageComponent#content as stated in the documentation.
Also make sure you enabled the correct intents and asked for verification if you bot is over 100 guilds.

Answer 3

You are missing an intents
Intents.FLAGS.DIRECT_MESSAGES,
Intents.FLAGS.DIRECT_MESSAGE_REACTIONS,
Intents.FLAGS.DIRECT_MESSAGE_TYPING,
or
const client = new Discord.Client({ intents: ["GUILDS", "GUILD_MESSAGES", "GUILD_MEMBERS","DIRECT_MESSAGES","DIRECT_MESSAGE_REACTIONS","DIRECT_MESSAGE_TYPING"] });

Answer 4

Go to the Discord developers site and make sure that your message content intents are turned on, and everything should work fine now.
