I'm unable to add or update environment variables on my services. When I try to add a variable, the UI shows "Applying 1 change" indefinitely and never completes.

Details:

• Project: zestful-consideration
• Environment: production
• Affected services: (backend), Front (frontend)
• Tried: Refreshing page, waiting several minutes

Steps to reproduce:

1. Go to service → Variables tab
2. Click "Add Variable"
3. Enter variable name and value
4. UI shows "Applying 1 change" and gets stuck

Expected: Variable should be saved and service should redeploy

Workaround needed: I need to set CORS_ORIGINS variable on my backend service to connect my frontend.
