如何修复反应不是 function discord.js？

Question

I've been struggling with this issue for quite a while, so I want to make my bot react with the emoji when someone reacts with on the same message. However, I'm getting this error whenever I react with. Error: TypeError: Cannot read property 'react' of undefined

Any kind of help is really appreciated, thanks.

client.on('messageReactionAdd', async (reaction,user) => {
     if (reaction.emoji.name === '🔒') {
            const msg = reaction.message.channel.id
            await msg.react('🚫')
        }   else if(reaction.emoji.name === '🚫'){
                const channelId = reaction.message.channel.id;
                if (channelId){
                    channelId.delete();
                    
                }
            } 
});

You are setting msg to the message's ID (which is a string), not to the message object. Replace the assignment with this one:

const msg = reaction.message;
