TypeError: options.getMember is not a function

so I have been coding the ban command, just finished it and I started getting this error. I have no idea how to fix it even though searching through the internet for a while now. Can someone help me with this one?

This is the error I am getting:

/Users/Aplex/Documents/Aplel/Commands/Moderation/ban.js:45
        const Target = options.getMember("target");
                               ^
