Hi, I'm having trouble with noding my mixed messages app

This is the project I am working on:https://www.codecademy.com/paths/full-stack-engineer-career-path/tracks/fscp-javascript-syntax-portfolio-project/modules/fscp-mixed-messages/kanban_projects/mixed-messages

The issue is that I used Visual Code, saved my app, then go in command line cd-ing to the directory, I can ls and see the file there, but if I “node 8ball.js” it throws the following error:

Error: Cannot find module ‘C:\Users[retracteduserid]\source\repos\8ball.js’
←[90m at Function.Module._resolveFilename (internal/modules/cjs/loader.js:902:15)←[39m
←[90m at Function.Module._load (internal/modules/cjs/loader.js:746:27)←[39m
←[90m at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:76:12)←[39m
←[90m at internal/main/run_main_module.js:17:47←[39m {
code: ←[32m’MODULE_NOT_FOUND’←[39m,
and it seems to me this means node couldn’t find the file I called, those ls shows it’s right there?

Thank you to anyone who can help.
