How can I check If a message exists in discord.js

I would like to have some kind of reaction roles into my bot. For that I have to test If the message ID that the User sends to the bot is valid. Can someone tell me how to do that?

This works for me (Discord.js v12)

First you need to define the channel where you want your bot to search for a message.
(You can find it like this) 

const targetedChannel = client.channels.cache.find((channel) => channel.name === "<Channel Name>");

Then you need to add this function: 

async function setMessageValue (_messageID, _targetedChannel) {
    let foundMessage = new String();
    
    // Check if the message contains only numbers (Beacause ID contains only numbers)
    if (!Number(_messageID)) return 'FAIL_ID=NAN';

    // Check if the Message with the targeted ID is found from the Discord.js API
    try {
        await Promise.all([_targetedChannel.messages.fetch(_messageID)]);
    } catch (error) {
        // Error: Message not found
        if (error.code == 10008) {
            console.error('Failed to find the message! Setting value to error message...');
            foundMessage = 'FAIL_ID';
        }
    } finally {
        // If the type of variable is string (Contains an error message inside) then just return the fail message.
        if (typeof foundMessage == 'string') return foundMessage;
        // Else if the type of the variable is not a string (beacause is an object with the message props) return back the targeted message object.
        return _targetedChannel.messages.fetch(_messageID);
    }
}

After this procedure, just get the function value to another variable:

const messageReturn = await setMessageValue("MessageID", targetedChannel);

And then you can do with it whetever you want.
Just for example you can edit that message with the following code:

messageReturn.edit("<Your text here>");

You can do that with .fetch() as long as you also know what channel you're looking in.

If the message is in the same channel the user sent the ID in then you can use message.channel to get the channel or if it's in another channel then you have to get that channel using its ID using message.guild.channels.cache.get(CHANNEL_ID).

So your code could be like this if it's in the same channel:

const msg = message.channel.messages.fetch(MESSAGE_ID)

or if it's in a different channel:

const channel = message.guild.channels.cache.get(CHANNEL_ID)
const msg = channel.messages.fetch(MESSAGE_ID)
