        uses: actions/github-script@v7
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
        with:
          script: |
            const output = `
            #### Helmfile Diff Results for Development ♠️
            <details><summary>Helm Diff Output</summary>

            \`\`\`
            Output
            ${{ steps.helmfile_diff.outputs.helmfile-stdout }}
            Errors (if any)
            ${{ steps.helmfile_diff.outputs.helmfile-stderr }}
            \`\`\`

            </details>`;

            github.rest.issues.createComment({
              issue_number: context.issue.number,
              owner: context.repo.owner,
              repo: context.repo.repo,
              body: output
            })

As you see, I do not expect the message if specified strings are not found and stderr is empty.
However, I get comment as below (result from Actions logs)

Run actions/github-script@v7
  with:
    script: const output = `
  #### Helmfile Diff Results for Development ♠️
  <details><summary>Helm Diff Output</summary>
  
  \`\`\`
  Output
  Comparing release=secret-creator, chart=secret-creator
  
  Errors (if any)
  Building dependency release=secret-creator, chart=secret-creator
  
  \`\`\`
  
  </details>`;
  
  github.rest.issues.createComment({
    issue_number: context.issue.number,
    owner: context.repo.owner,
    repo: context.repo.repo,
    body: output
  })

Expected:
No generic messages in stderr.
Thank you for considering the issue.

@abseht Do you wish helmfile diff return empty when no diff?

[abseht]

@yxxhero i think it is fair to return some message as "...nothing to apply..." and people will use it as they please.

[yxxhero]

@abseht yeah. you can post an feature request in helmd-diff project.

[abseht]

@yxxhero this issue is about not logging 'stderr' if there is no errors.

[yxxhero]

ok
