failed to compile nginx-buildpack app

[DoubleCouponDay]

While invoking git push heroku master, I run into a problem with my configuration of .nginx-buildpack.

remote: -----> nginx-buildpack app detected
remote: cp: cannot stat 'bin/nginx-heroku-16': No such file or directory
remote:  !     Push rejected, failed to compile nginx-buildpack app.

I tried creating the bin/nginx-heroku-16 directory manually, then pushing changes to my repository, but the problem was not fixed. here's a look at my root directory.

Here's a look at my app configuration on heroku:

I have no idea what is causing this. Please assist :)

I think this buildpack may no longer work and is no longer maintained @DoubleCouponDay
