Answer 1

this problem arises when you have some file that is not yet added and committed to git.

git add .
git commit -m "commit done"
git push heroku master

Answer 2

I had the same problem, the solution was

in my branch, called "testBranchSuper"

i use

git checkout -b main

and then i use

git push heroku main

Answer 3

It is probably due to an Outdated yarn.lock file

Just run the following commands

yarn install
git add yarn.lock
git commit -m "Updated Yarn lockfile"
git push heroku master

Answer 4

If you want to push commit on git repository, plz make sure you have merged all commit from other branches.

After merging if you are unable to push commit, Use the push command with -f

git push -f origin branch-name

Where origin is the name of your remote repo.

Answer 5

This error means that the upstream repository has made commits that would be lost if you were to push. First do a "git pull" to merge, and then push again.

Answer 6

Another issue could come from the use of backticks, those are not supported by the compiler (uglifier).

To fix it, replace config.assets.js_compressor = :uglifier with config.assets.js_compressor = Uglifier.new(harmony: true).
