#Crash because of undefined _sharedAddOptionMethod — Page 1

I created a CommandConstructor but when adding options to it, it always gives me following error:

WizRepoBot\node_modules\@discordjs\builders\dist\index.js:1335
    return this._sharedAddOptionMethod(input, SlashCommandStringOption);
                ^

TypeError: Cannot read properties of undefined (reading '_sharedAddOptionMethod')
