This is the error that is triggering a P0 incident in Chatwoot.
```
DashboardController#index is missing a template for this request format and variant. request.formats: ["application/json"] request.variant: []
```
The user is calling `/app/accounts/api/v1/accounts/<account-id>/inboxes`. The URL is wrong, the requests are routed to dashboard controller as it starts with `/app/accounts`. The dashboard controller is not handling JSON requests and it creates errors. There are 312k errors over the last 2 years. Close to 50k during last 3 days.
This fix would return not_acceptable response to the attempts.
