${Key}.${NestedKeyOf<ObjectType[Key]>}. this line gives me an error when typescript version is 4.6.4 & 4.7.4 (latest) ->

Type instantiation is excessively deep and possibly infinite. Can you explain why and can you please also add the return type.

use

`${Key}.${NestedKeyOf<ObjectType[Key]> extends infer U extends string ? U : never}`
Enter fullscreen mode Exit fullscreen mode

instead of

${Key}.${NestedKeyOf<ObjectType[Key]>}
Enter fullscreen mode Exit fullscreen mode
