I am using Heroku and trying to deploy my code, but when I try to deploy I get an error.

It says it does not detect any build packs, but I have done a version check and have the latest Node.js installed.

Is there something I am missing?

terminal:

Still, following the documentation mentioned in the error message, try and set a buildpack explicitly:

heroku buildpacks:set heroku/nodejs

This situation may also occur if you remove or rename a file that previously led to the automatic detection of your application type and thus the automatic setting of the detected buildpack on your application.

Check also the answer for this question, and your package.json content.
As seen here, that package.json and Procfile must be at the root folder of your project.
