Newline \n in latest release is ignored compared to previous one

[jprecuch]

Previously I've send this variable to this slack action

            {
              "type": "rich_text_preformatted",
              "elements": [
                {
                  "type": "text",
                  "text": "${{ env.VERSION_SUMMARY_OUTPUT }}"
                }
              ]
            },

with variable containing:

anf-rp             2537.0.0-main.3  installed  deployed\nazure-monitor      installed        install\nazure-redis        6.0              installed\nazure-service-bus  1.0              installed\ncbs                2537.0.0-main.2  installed  deployed\ncvo                9.17.1           installed\ncvs-sde            2537.0.0-main.7  installed  deployed\nmanaged-identity   installed        install\nmoonstone          v0.2.56          installed  deployed\nnfsaas-azurite     v1.4.0           installed  deployed\nnrp-simulator      v0.19.0          installed  deployed\nrabbitmq           v1.19.0          installed  deployed\ntimescaledb        0.0.8            installed  deployed%

This made all \n newlines and hence everything was on newline after it.
After using latest slack-github-action this changed and is shown exactly like above (with the \n as text).
How to preserve the newlines with latest release? See attached files before/after

Hey @jprecuch! 👋 Thanks for sharing this example for troubleshooting! 🏗️ 📚

Adding variables with newlines to existing JSON might require using the toJSON method to escape these newlines for the workflow? These examples are seeming alright for me at the moment:

- name: Post rich text preformatted newlines with YAML
  uses: slackapi/slack-github-action@v2.1.1
  env:
    VERSION_SUMMARY_OUTPUT: "anf-rp             2537.0.0-main.3  installed  deployed\nazure-monitor      installed        install\nazure-redis        6.0              installed\nazure-service-bus  1.0              installed\ncbs                2537.0.0-main.2  installed  deployed\ncvo                9.17.1           installed\ncvs-sde            2537.0.0-main.7  installed  deployed\nmanaged-identity   installed        install\nmoonstone          v0.2.56          installed  deployed\nnfsaas-azurite     v1.4.0           installed  deployed\nnrp-simulator      v0.19.0          installed  deployed\nrabbitmq           v1.19.0          installed  deployed\ntimescaledb        0.0.8            installed  deployed%"
  with:
    token: ${{ secrets.SLACK_BOT_TOKEN }}
    method: chat.postMessage
    errors: "true"
    payload: |
      channel: "${{ secrets.SLACK_CHANNEL_ID }}"
      text: "${{ env.VERSION_SUMMARY_OUTPUT }}"
      blocks:
        - type: rich_text
          elements:
            - type: rich_text_preformatted
              elements:
                - type: text
                  text: ${{ toJSON(env.VERSION_SUMMARY_OUTPUT) }}
              border: 0

Or:

- name: Post rich text preformatted newlines with JSON
  uses: slackapi/slack-github-action@v2.1.1
  env:
    VERSION_SUMMARY_OUTPUT: "anf-rp             2537.0.0-main.3  installed  deployed\nazure-monitor      installed        install\nazure-redis        6.0              installed\nazure-service-bus  1.0              installed\ncbs                2537.0.0-main.2  installed  deployed\ncvo                9.17.1           installed\ncvs-sde            2537.0.0-main.7  installed  deployed\nmanaged-identity   installed        install\nmoonstone          v0.2.56          installed  deployed\nnfsaas-azurite     v1.4.0           installed  deployed\nnrp-simulator      v0.19.0          installed  deployed\nrabbitmq           v1.19.0          installed  deployed\ntimescaledb        0.0.8            installed  deployed%"
  with:
    token: ${{ secrets.SLACK_BOT_TOKEN }}
    method: chat.postMessage
    errors: "true"
    payload: |
      {
        "channel": "${{ secrets.SLACK_CHANNEL_ID }}",
        "text": "${{ env.VERSION_SUMMARY_OUTPUT }}",
        "blocks": [
          {
            "type": "rich_text",
            "elements": [
              {
                "type": "rich_text_preformatted",
                "elements": [
                  {
                    "type": "text",
                    "text": ${{ toJSON(env.VERSION_SUMMARY_OUTPUT) }}
                  },
                ],
                "border": 0
              }
            ]
          }
        ]
      }

Please let me know if either of these is alright for you! This can be a good case to include in documentation if so- 👁️‍🗨️

I will close this issue. It seems the \n was required with previous version. With latest version need for it is gone and multilines work by default now
