FLOW BUG: This is a misplaced error about flow HOT 3 OPEN

Can you try replacing your $ObjMap with mapped types? https://flow.org/en/docs/types/mapped-types/

from flow.

The error is correct, the BUG refers to the fact that the error is misplaced: it's raised as a result of checking file a but raised in file b. Our LSP implementation assumes this doesn't happen, so it results in confusing experience in your IDE. If you want help fixing the error, you will need to include more context.

I see. I can try to migrate to mapped types.

However, this syntax works in TypeScript playground but doesn't work in Flow playground
Please let me know if there's a better syntax for it:

declare function f(s: string, n?: number): boolean;
type Tuple = Parameters<typeof f>;
declare function g(...args: Parameters<typeof f>): boolean;
g("hi")

from flow.
