Worked on the hey-api/openapi-ts repository to address a type inference issue in TanStack Query’s infinite query options. Focused on aligning the generated TypeScript typings with actual runtime behavior, the developer removed the phantom requirement for initialData, which previously led to type mismatches for consumers using useInfiniteQuery without initial data. By binding generated options to a constant and omitting the initialData property, the fix improved type safety and reduced errors in query management workflows. This targeted bug fix, implemented in TypeScript, enhanced the reliability of type inference for developers integrating infinite queries, ensuring more accurate and maintainable codebases.
