I’m trying to pass a generic type argument using typeof. The variable may be undefined, but the generic type argument does not allow undefined.

// T cannot be undefined
type SomeType<T extends object> = {
  // ...
};

// variable may be undefined
const data: object | undefined = undefined;

type OtherType = SomeType<typeof data>;
// Error                  ^
// Type 'undefined' does not satisfy the constraint 'object'

How can I get around this error, so that OtherType is either undefined or the returned type from SomeType<T>? I thought this might be the answer, but I still get the same error.

type OtherType = typeof thing extends undefined
  ? undefined
  : SomeType<typeof thing>;
