Heroku ERROR: Failed parsing composer.lock; it must be non-empty and valid JSON

Currently getting this error and not sure how to fix, I ran composer update but that didn't resolve it.

$ git push

   Run 'composer update' to have it re-generated or removed by Composer.

I just had exactly the same problem. However after double checking the lock file was valid JSON and was a valid file.

Solution turned out to be updating composer itself "composer self-update" to the latest version then it worked fine
