...
commands:
E:\Coding\projects\instagram>git add .
E:\Coding\projects\instagram>git commit -m "update controllers"
[master 086d891] update controllers
1 file changed, 1 insertion(+), 1 deletion(-)
E:\Coding\projects\instagram>cd backend
E:\Coding\projects\instagram\backend>git push -f heroku master
after the last command (git push -f heroku master) i got this error:

Heroku buildpack looks at the top-level (root) for package.json.
The solution here is to use git sub-trees. I too was facing this issue where I had a Monorepo MERN codebase in which I wanted to deploy my server using Heroku and client via Vercel.
I have written a blog post regarding this, I'm sure you'll get an idea regarding a solution to this.
