todos job failing

[ＤＯＬＬＦλＣＥ]

Hi!

I've been trying to setup this action into one of my repositories, and I'm getting this error in the `todos' job:

error: failed to push some refs to '***github.com/walizw/GeometryDash.git'
hint: Updates were rejected because a pushed branch tip is behind its remote
hint: counterpart. Check out this branch and integrate the remote changes
hint: (e.g. 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

  status: 1,

  output: [ null, null, null ],

}

Is it something wrong with my yaml file? How can I fix it? Thank you so much if you can help me!
