I'm coding a Discord Bot in JavaScript, but I have this error when I launch the bot ! I don't find because I check the "application.commands" box! Here's the full error message:

I don't know how I can resolve the problem :(

I try to invite my bot another time, but it doesn't work :(

The error message who makes problems :

CodePudding user response：

it's referring to this line here:

client.guilds.cache.get("1027595307187441664").commands.create(thumbnail);

Basically client.guilds.cache.get("1027595307187441664") is undefined and did not return a result.
