How to use multiline variable in a script#458

I am having trouble using a multiline variable in thescript part of actionactions/github-script@v6.

I found out how to convert it to a one line string, and this works fine in therun part of a second step. For example, this works:

    steps:    - name: Step1      id: stepone      run: |        long_test_string="line one          line two          line three"        echo "Long test string:"        echo $long_test_string        LONG2=${long_test_string}        LONG2="${LONG2//'%'/'%25'}"        LONG2="${LONG2//$'\n'/'%0A'}"        LONG2="${LONG2//$'\r'/'%0D'}"        echo "long2=$LONG2" >> "$GITHUB_OUTPUT"           - name: Step2      run: |        echo "${{ steps.stepone.outputs.long2 }}"

However, when I try to display this in a PR comment, I get an error.

    - name: Step3      uses: actions/github-script@v6      with:        script: |            github.rest.issues.createComment({              issue_number: context.issue.number,              owner: context.repo.owner,              repo: context.repo.repo,              body: "${{ steps.stepone.outputs.long2 }}"            })

I'd recommend passing inputs through an environment variable into your script rather than inlining the expression.

https://github.com/actions/github-script#use-env-as-input

For example:

    -name:Step3uses:actions/github-script@v6env:LONG_OUTPUT:${{ steps.stepone.outputs.long2 }}with:script:|            github.rest.issues.createComment({              issue_number: context.issue.number,              owner: context.repo.owner,              repo: context.repo.repo,              body: process.env.LONG_OUTPUT            })
