Skill: Wix-GAS Bridge Integrity Check

Use this skill when:

• Submissions are not appearing in GAS.
• "Success" message appears but no data moves.
• You receive 500 or 404 errors from the GAS endpoint.

Step 1: Verify Secrets

The connection relies on GAS_WEB_APP_URL and GAS_API_KEY.

1. Action: Ask user to check Wix Secrets Manager.
2. Check: Does GAS_WEB_APP_URL end in /exec? (Common fatal error: ending in /edit)

Step 2: Live Log Trace

Run this trace to see where the packet drops.

1. Frontend: Console > "Submitting form..."
2. Backend: intakeQueue.jsw > "Sending to GAS..."
3. GAS Side: View Stackdriver Logs (Executions). Do you see a POST request?

Step 3: The "Push" Simulation

If the bridge is down, force a manual push to test connectivity.

// Run this in a temporary backend file to test connection
import { notifyGASOfNewIntake } from 'backend/gasIntegration';

export async function testBridge() {
    const result = await notifyGASOfNewIntake('TEST-CASE-ID-001');
    console.log(result);
}

Step 4: Common Fixes

• Redirect Loop: If GAS returns 302, your script is not deployed as "Web App" with "Execute as: Me" and "Who has access: Anyone".
• CORS Error: GAS does not support CORS preflight. Use POST with application/x-www-form-urlencoded or JSON properly stringified.
