Restore lowercase normalization for the GHCR image reference.
${{ github.repository }} resolves to Shashank0701-byte/System-Craft, which produces an invalid uppercase Docker repository name. Use one normalized reference for the build, Trivy scan, E2E container, and push steps. Match ghcr.io/shashank0701-byte/system-craft/systemcraft-web used by the deployment manifests.

GitHub Actions GITHUB_TOKEN permissions issues.createComment issues.addLabels pull_request_target fork pull requests write permission
💡 Result:
The issue arises because GitHub Actions restricts the GITHUB_TOKEN to read-only permissions for pull requests originating from forked repositories when using the standard pull_request event, even if you explicitly define write permissions in your workflow [1][2][3]. This is a security measure designed to prevent unauthorized code from executing with elevated privileges [4][3]. To enable operations like issues.createComment or issues.addLabels on fork pull requests, you must use the pull_request_target event [1][2][5]. Key Considerations for pull_request_target: 1. Trusted Context: Unlike pull_request, which runs the workflow using the commit from the pull request head (which is untrusted), pull_request_target runs using the workflow definition from the base repository's default branch [4][3]. This allows it to run with the base repository's write-capable GITHUB_TOKEN and access to repository secrets [4][3]. 2. Security Warning: Because pull_request_target runs with elevated trust, you must strictly avoid checking out and executing code from the untrusted fork [6][3][7]. If a workflow triggered by pull_request_target checks out the PR head and runs scripts (e.g., npm install, build commands), an attacker can exploit this to gain access to secrets or the repository's write-enabled token [6][3][7]. 3. Implementation: Use pull_request_target only for trusted, code-free automation tasks such as adding labels, posting comments, or basic triage [3][7]. Ensure your workflow explicitly requests the necessary permissions in your YAML file [8]: permissions: contents: read pull-requests: write issues: write If you need to perform builds or tests on fork contributions, do so in a separate workflow triggered by the pull_request event, which remains safely sandboxed with read-only permissions and no access to secrets [3][7].

site:docs.github.com/rest/issues/comments create an issue comment GitHub Actions GITHUB_TOKEN pull requests write issues write
💡 Result:
To create an issue comment in GitHub Actions using the GITHUB_TOKEN, you must configure the workflow to have the necessary permissions and then use the GitHub REST API. Permissions Configuration To perform write operations such as creating comments on issues or pull requests, you must explicitly grant the GITHUB_TOKEN write access in your workflow file. Add the following permissions block to your job or workflow: permissions: issues: write pull-requests: write Creating the Comment Once the permissions are configured, you can create a comment by making a POST request to the GitHub REST API endpoint: POST /repos/{owner}/{repo}/issues/{issue_number}/comments [1]. Since every pull request is considered an issue by the API, this endpoint works for both issues and pull requests [1]. You can implement this using the GitHub CLI (gh) or cURL. If you are using the default GITHUB_TOKEN, the GitHub CLI is often pre-authenticated. Example using the GitHub CLI: gh api repos/{owner}/{repo}/issues/{issue_number}/comments -f body='Your comment text here' If using cURL, ensure you include the authorization header with your token: curl -L \ -X POST \ -H "Accept: application/vnd.github+json" \ -H "Authorization: Bearer ${{ secrets.GITHUB_TOKEN }}" \ https://api.github.com/repos/{owner}/{repo}/issues/{issue_number}/comments \ -d '{"body":"Your comment text here"}'
Citations:
Use a trusted trigger for write actions.
Fork pull requests can receive a read-only GITHUB_TOKEN under pull_request, so the checklist comment and label steps can fail. Use pull_request_target for this metadata-only workflow. Do not check out or execute pull request code in this workflow.
