#My bot can't speak when running on heroku — Page 1

My bot works fine when running on my pc, but when I deploy it to heroku, it can't speak. It connects on the channel but doesn't speak, and I get no errors on the console.

const { generateDependencyReport } = require('@discordjs/voice');
console.log(generateDependencyReport());

Running this code on heroku I get this output.
