The process "git" failed with exit code 8

[vivekvc2021]

Bug Description
I tried pushing one of my changes to my website, and it normally works but for some reason my pushes started erroring with exit code 8. Why is this, and how do I fix it?

My Action Config

on: 
  push:
    branches:
      - master
name: Publish Website
jobs:
  FTP-Deploy-Action:
    name: FTP-Deploy-Action
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@master
      with:
        fetch-depth: 2
    - name: FTP-Deploy-Action
      uses: SamKirkland/FTP-Deploy-Action@3.0.0
      with:
        ftp-server: ${{ secrets.FTP_HOST }}
        ftp-username: ${{ secrets.FTP_USER }}
        ftp-password: ${{ secrets.FTP_PASS }}
