+# PVTR Action Test
+
+This repository contains tests for the PVTR (Privateer) action and fixes for common SARIF upload issues.
+
+## SARIF Upload Fix
+
+This repository includes a fix for the common CodeQL SARIF upload error:
+```
+Invalid request. 1 item required; only 0 were supplied.
+```
+
+### Root Cause
+
+This error occurs when the SARIF file has an empty `runs` array or missing required properties. While the SARIF file may pass local validation, GitHub's CodeQL API has stricter requirements.
+
+### Solution
+
+The `validate-sarif.sh` script:
+
+1. **Validates** the SARIF file structure
+2. **Detects** empty runs arrays that cause the upload error
+3. **Fixes** malformed SARIF files by adding a minimal valid run structure
+4. **Preserves** existing valid SARIF files unchanged
+
+### Usage
+
+The workflow automatically uses the validation script before uploading SARIF files:
+
+```yaml
+- name: Validate and fix SARIF file
+  id: fix_sarif
+  run: |
+    if ! command -v jq &> /dev/null; then
+      sudo apt-get update && sudo apt-get install -y jq
+    fi
+    ./validate-sarif.sh "${{ steps.scan.outputs.sarif_file }}"
+
+- name: Upload SARIF file
+  uses: github/codeql-action/upload-sarif@v3
+  with:
+    sarif_file: ${{ steps.fix_sarif.outputs.sarif_file }}
+    category: OSPS Baseline
+```
+
+### Manual Usage
+
+```bash
+./validate-sarif.sh path/to/file.sarif
+```
+
+The script will either:
+- Output the original file path if valid
+- Create a fixed version and output the fixed file path
+
+### Files
+
+- `.github/workflows/action-test.yml` - Main workflow that runs the PVTR scanner
+- `validate-sarif.sh` - SARIF validation and fixing script
