Argument of type '"/_layout/child"' is not assignable to parameter of type 'keyof FileRoutesByPath'.

Looking at the official document, I'm making a child file wrapped in layout, and the code keeps getting the same error as the picture, can you tell me what the problem is?

sometimes the routeTree.gen.ts file is open and needs to be closed/reopened for TS to properly parse it.

Such an simple solution, Thanks.
