I'm trying to send a message to a specific channel on discord, however gives me this error :

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

I've entered the correct channel id though, what could be the issue ? Here's my function code and a snapshot :

function discordsend(usern)
{ 
    usern="someusername#1234"
    string = "somethingsomething"+usern;
    const channel = client.channels.cache.get('946932969359179786');
    channel.send(string);
}
