Typescript error when extracting param matches when param is on the root route

I see

Property 'accountId' does not exist on type 'Record<never, string>

Property 'accountId' does not exist on type 'Record<never, string>

when using this param on the root route. I might just be using it wrong though. The param does exist at runtime, so it is found correctly.
