I have problem with discord.js script, my script copied directly from discordjs guide

I work for a well known company and we are looking for a way to ensure that only users of our website with an account in good standing can join and remain on our discord server. I am having trouble finding a way to do that.

I have a bot and I want to send a message if the content of the last message sent (in the same channel) is not equal to the content of the message I want to send

I’m here because I’d like to know how to create custom error messages like this one. I couldn’t find the solution anywhere.

I want it so that after my bot has sent an embed it adds a checkmark reaction
This is my code
