# Breaking: #72474 - RequestHandler only works with Routes

See [forge#72474](https://forge.typo3.org/issues/72474)

## Description

The default backend RequestHandler had a fallback that triggered the backend initialization without having
a `&route=` request parameter set. This was used for the transition when deprecating the traditional entry-scripts. The
logic has been removed.

## Impact

Any regular backend request (non-module and non-AJAX) will now require a
`&route=` request parameter, otherwise will fallback to the default route
(login) when not provided.

## Migration

For all backend-related calls, either use a custom RequestHandler or switch to Backend Routing.
