Discord-user-bots How to send a file?

I'm trying to send a .txt file but everytime I try it's return an error (which I don't understand). Does someone know how to send a file?

What is the error you're receiving? What's the code you're using to send a .txt file?

Oh sorry I didn't saw the comment. Here's the error:

node:internal/deps/undici/undici:11118
    Error.captureStackTrace(err, this);
          ^
