 - Add `/** @ts-expect-error */ ` (make sure to use this exact comment format otherwise they will be missing from `d.ts` files) for imports for `ImageSizeRequest`, `OnlyUserIDRequest` in the `gen/chat/FilesApi.ts` and `gen/chat/MessagesApi.ts` files
 - Add `/** @ts-expect-error */ ` (make sure to use this exact comment format otherwise they will be missing from `d.ts` files) for duplicate exports in `gen/chat/index.ts`
-- Fix the query param serizalization in the `gen/chat/MessagesApi.ts` file's `getManyMessagesRaw` function. This is the correct serialization:

-if (requestParameters.ids) {

-}
