Typescript reports circular dependency error in Record type but not in dynamic object type

[ritikbanger]

I have two kinds of type, while using the Record, typescript is giving circular reference error. But when I do the same with a dynamic object, no error pops. Why typescript show two completely contrasting behaviours?

The expected output should be error on both or on none.

type ScopeItem =
    | string
    | {
            all: string;
            team: string;
      };

type ScopesTree = Record<string, ScopeItem | Record<string, ScopesTree>>; // error: Type alias 'ScopesTree' circular references itself
type ScopesTree2 = Record<string, ScopeItem | { [key: string]: ScopesTree2 }>; // no error

Is it something to do with the computation of the typescript type in both the cases? Please enlighten.

Thanks.
