To Reproduce Steps to reproduce the behavior:

1. Go to: Server Settings > Policies
2. Click on: Display app on website root
3. Select from dropdown: Any POS app
4. Click Save
5. Open browser to root domain to see POS App
6. Page gives 500 error

Expected behavior POS App appears on the root domain

Actual behavior 500 error shows for root domain

Additional context Setting a Crowdfund App on root domain does not have the issue
