PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
Possible issue	Correct the type for validateStatus Correct the validateStatus type to ((status: number) => boolean) | null, allowing the property itself to be null instead of allowing the callback function to return null. index.d.ts [65] -validateStatus?: ((status: number) => boolean | null); +validateStatus?: ((status: number) => boolean) | null; Apply / Chat Suggestion importance[1-10]: 8 __ Why: The suggestion correctly identifies that the validateStatus property can be null to use default behavior, but the callback function itself should always return a boolean, thus correcting the type definition to match the library's API.
