PR Close#18541
Previously the RequestOptions/ResponseOptions classes had constructors
with a destructured argument hash (represented by the
{Request,Response}OptionsArgs type). This type consists entirely of
optional members.
This produces a .d.ts file which includes the constructor declaration:
constructor({param, otherParam}?: OptionsArgs);
However, this declaration doesn't type-check properly. TypeScript
determines the actual type of the hash parameter to be OptionsArgs | undefined,
which it then concludes does not have a `param` or `otherParam` member.
This is a bug in TypeScript ( https://github.com/microsoft/typescript/issues/10078 ).
As a workaround, destructuring is moved inside the method, where it does not produce
broken artifacts in the .d.ts.
Fixes#16663.
