I'm trying to create my first Github Actions workflow and am getting an error that online research isn't helping me resolve. This is a pretty basic workflow at this point for a WordPress site. It is failing on the line "fetch-depth: 0". I've been checking the indentation and looking at examples online.

 name: deploy
on:
 push:
 branches:
 # Pushing to the `master` branch
 # will trigger our workflow
 - master
 paths-ignore:
 # Ignore files and folders
 - 'bin/**'
 - 'readme.html'
concurrency:
 #maximum of one deployment in progress and one deployment pending at a time
 group: ${{ github.workflow }}-${{ github.ref }}
 cancel-in-progress: true
permissions:
 actions: write
 contents: read
jobs:
 deploy:
 runs-on: ubuntu-latest
 steps:
 - name: Checkout
 # Checkout our repository under `${GITHUB_WORKSPACE}`,
 # so our workflow can access it
 uses: actions/checkout@v3
 with:
 # Fetch the entire Git history. 
 fetch-depth: 0

 - name: Deploy via SFTP
 #Deploy via FTP details
