I followed the step to upload my backend to Heroku from this video: https://www.youtube.com/watch?v=rSkxia0ZZQ0, and I got this error:

Answer 1

Heroku sees that you made some changes in your visual studio code or what are you using and it's telling you that you didn't push on git the last version of your app.
remote: ! ## Warning - The same version of this code has already been
built: aad8206689cb2d86d27ef0e2a124aa9701bf8a7b remote: ! remote: !
We have detected that you have triggered a build from source code with
version aad8206689cb2d86d27ef0e2a124aa9701bf8a7b
You need to commit your changes in the project and push them to git and after you can push the git on the heroku server.
