Hard to see how this particular implementation could have worked. I see you are using discord.js 13.1.0 but node 14.17.3 (you will need to specify a more recent version of node like 16.6.1. Also you have npm and node in your list of runtime dependencies which should be there and if fs is the “file system” then it doesn’t need to be installed separately.
