Unexpected token ' in JSON at position 0 | Multiline client_payload

[justmike1]

So I am trying to implement a multiline client_payload, my configuration:

  call-gke-cd:
    if: >
      ${{
      (startsWith(github.event.head_commit.message, '[PROD]:')) || 
      (github.ref != 'refs/heads/master')
      }}
    name: CD / Deploy to Kubernetes
    runs-on: ubuntu-22.04
    needs: [affected-services, build-and-push-docker]
    steps:
      - name: Repository Dispatch
        uses: peter-evans/repository-dispatch@v2
        with:
          token: ${{ secrets.GIT_ACCESS_TOKEN }}
          repository: myorg/myrepo
          event-type: deploy
          client-payload: >
            '{"ref": "${{ github.ref }}", 
            "image_tag": "${{ needs.affected-services.outputs.project_version }}", 
            "services": "${{ needs.affected-services.outputs.matrix }}"}'

I get fails of Unexpected token ' in JSON at position 0

Hi @justmike1

This site might help you:
https://yaml-multiline.info/

You probably want >-, but I'm not sure.

          client-payload: >-
            '{"ref": "${{ github.ref }}", 
            "image_tag": "${{ needs.affected-services.outputs.project_version }}", 
            "services": "${{ needs.affected-services.outputs.matrix }}"}'

Or it might be complaining about the quotes. Try removing them.

          client-payload: >-
            {"ref": "${{ github.ref }}", 
            "image_tag": "${{ needs.affected-services.outputs.project_version }}", 
            "services": "${{ needs.affected-services.outputs.matrix }}"}

The following works well for me:

    steps:
      - name: Trigger Container Build and Deploy
        uses: peter-evans/repository-dispatch@v2
        with:
          token: ${{ secrets.CI_WEBHOOK_TOKEN }}
          repository: mystuff/ci-docker
          event-type: build-repo
          client-payload: |-
            {
              "repo": {
                "name": "${{ github.repository }}",
                "branch": "${{ needs.build_cfg.outputs.REPO_BRANCH }}",
                "tag": "${{ needs.build_cfg.outputs.REPO_TAG }}"
              },
              "image": {
                "dockerfile": "Dockerfile",
                "name": "${{ github.repository }}",
                "tag": "${{ needs.build_cfg.outputs.VERSION_STR }}",
                "build_args": [
                  "VERSION=${{ needs.build_cfg.outputs.VERSION_STR }}"
                ]
              },
              "deployment": {
                "project": "${{ env.MY_PROJECT }}",
                "container": "${{ env.MY_CONTAINER }}",
                "deploy_msg": "${{ env.SLACK_DEPLOY_MSG }}",
              }
            }

cool, thanks!

Could we add a multiline example to the docs? It took a while to find this...
