Used Package Manager

npm

Expected Behavior

Defining the server component as

export const ServerComponent = ({}: Route.ComponentProps) => …

yields correct types and no type error

Actual Behavior

We get the type error

TS7022: 'ServerComponent' implicitly has type 'any' because it does not have a type annotation and is referenced directly or indirectly in its own initializer.

Workaround: Define function as

export const ServerComponent: (props: Route.ComponentProps) => JSX.Element = ({}) => …

Digging into this a bit, I'm getting a Type alias 'ComponentProps' circularly references itself. (2456) for the generated route types.
