Не получается сделать push в heroku выходит ошибка error: failed to push some refs

Не получается сделать push в heroku выходит следующее:

Some possible problems:
remote:
remote:        - Node version not specified in package.json
remote:          https://devcenter.heroku.com/articles/nodejs-support#specifying-a-node-js-version
remote:

To https://git.heroku.com/tabel-tasks.git
 ! [remote rejected] main -> main (pre-receive hook declined)
error: failed to push some refs to 'https://git.heroku.com/tabel-tasks.git'

В package.json - добил версию node, но проблема не изменилась. В чем может быть проблема? Буду рад любой помощи.
