Applications commands are registered throug rest api but not working

Hello, I am having a bit of a problem.. I a file named command.handler.ts. This file is responsible for loading commands and registration of them through the rest api. This works fine and my test command is also available in my server. However, when I execute the command nothing happens. I am not also not getting any output when I try to console.log(). The event for INTERACTION_CREATE is also being registered.. so I am not getting why it does not work

Inside the ready event I am registering the application commands. I am also getting the success message of the ready event so the events are working as intended. I do not get any errors logged just the discord message "The application did not respond" So I assume it handles the command somewhere but console.log() in different places does not log anything

treble/luna•12mo ago

the name is interactionCreate Or use the Events enum as alternative

darby•12mo ago

Huh.. okay when I logged GatewayDispatchEvents it logged "INTERACTION_CREATE" that's wyh I thought its named like that Okay, so I get the logging now when it hits the handleInteraction. But now is a point where I don't know anymore.. I am using the CommandInteraction type which does have the function isChatInputCommand But now I just get the error

error: Error while handling interaction! Error: TypeError: interaction.isChatInputCommand is not a function

error: Error while handling interaction! Error: TypeError: interaction.isChatInputCommand is not a function

No stack trace whatsoever just this message

Youssef•12mo ago

I think you should use BaseInteraction instead of ComamndInteraction

darby•12mo ago

But BaseInteraction does not have the .reply function I have in my ping command to test if it's working Also I am getting the same error that isChatInputCommand() is not a function :/ Okay, so I tried to log the commandName but it's undefined somehow Hitted handleInteraction()! undefined - undefined It ain't adding up tho lmao
