My Shopify app is missing the internal webhook route and webhooks are failing with 404 errors.
Problem: The Shopify webhook endpoint
/api/connections/shopify/events
/api/connections/shopify/events
returns 404.
Evidence: 1. Shopify webhooks are successfully registered in Shopify (16 webhooks) 2. When Shopify sends webhooks, they fail with: "No route matches URL '/api/connections/shopify/events'" (see production logs from today around 13:16:44) 3. The webhook URL is missing from Settings → Plugins → Shopify (only the GDPR webhook URL is visible)
History: This was working 3 days ago. Since then, webhooks stopped arriving.
