Destination missing when built with custom route override

[janseeger]

I am currently migrating code from v1 (1.11.9) to v2 (2.1.0) and have encountered an issue where some Destinations are not built and are thus missing after the KSP ran.

@Destination(
    route = "inbox",
    deepLinks = [
        DeepLink(uriPattern = PREFIX_URI1 + FULL_ROUTE_PLACEHOLDER),
        DeepLink(uriPattern = PREFIX_URI2 + FULL_ROUTE_PLACEHOLDER),
    ],
)
@Composable
fun InboxWithMoreComplexNameThanJustInbox()

works and generates the correct code, but when converted to v2

@Destination<InboxGraph>(
    route = "inbox",
    deepLinks = [
        DeepLink(uriPattern = PREFIX_URI1 + FULL_ROUTE_PLACEHOLDER),
        DeepLink(uriPattern = PREFIX_URI2 + FULL_ROUTE_PLACEHOLDER),
    ],
)

it stops working unless the route parameter is removed. But then the Deep Links stop working.

Any advice?
