req.query is undefined

and also typescript issue

Property 'query' does not exist on type 'RestRequest<DefaultRequestBody, RequestParams>'

Hey, @zkindest.

MSW does not have a custom query property on the request object. Instead, we use the standard URLSearchParams under req.url.searchParams. Learn more about working with query parameters.

In your example, accessing the query parameters would look like this:

const threadId = req.url.searchParams.get('thread_id')
