  -H "Accept: application/vnd.github+json" \
  "https://api.github.com/repos/marypas74/InsightLearn_WASM/dependabot/alerts/1" \
  -d '{
    "state": "dismissed",
    "dismissed_reason": "fix_started",
    "dismissed_comment": "Fixed in commit 7988953 - System.Data.SqlClient updated to 4.8.6"

Troubleshooting

Issue: GitHub CLI Not Found

bash: gh: command not found

Solution:

# Rocky Linux / RHEL
sudo dnf install -y gh

# Ubuntu / Debian
sudo apt install gh

# macOS
brew install gh

Issue: Authentication Failed

Issue: Alerts Still Showing After 48 Hours

Possible Causes:

  1. GitHub Dependabot scan hasn't run yet (runs every 24h)
  2. Package versions not detected correctly
  3. Manual dismissal required

Solution:

  • Wait additional 24 hours for next scan cycle
  • Use automated script: ./dismiss-github-alerts.sh
  • Manually dismiss via web UI (see Option 2 above)

Issue: "No Permission to Dismiss Alerts"

Error:

Resource not accessible by personal access token

Solution:

  • Verify you have "Write" access to repository
