How to pass null body through playwright request?

I have a POST request with null as the body. I am not sure how to pass this null through a Playwright POST request.

I tried with data: null, data: 'null', data: Null, data: '%00', data: {}. All these fails the test at the line where I catch the response body as await resp.body().

If I pass null in Postman for the same request, I get a successful JSON response. If no null in the Postman request, I get ‘content type error’ as response.
