Why am I getting 'Argument type is not assignable to parameter type ProcedureResolver<unknown>'?

I have this warning in my editor (jetbrains InteliJ):

Argument type () => any[] is not assignable to parameter type ProcedureResolver<unknown, unknown, unknown, unknown, unknown, unknown>

Argument type () => any[] is not assignable to parameter type ProcedureResolver<unknown, unknown, unknown, unknown, unknown, unknown>

Argument type () => any[] is not assignable to parameter type ProcedureResolver<unknown, unknown, unknown, unknown, unknown, unknown>

Argument type () => any[] is not assignable to parameter type ProcedureResolver<unknown, unknown, unknown, unknown, unknown, unknown>

I am using:
- Node V20.10.0
- pnpm 8.15.1
- trpc client/server 11.0.0-next-beta.257
