Cannot read the payload from a post request (didn't try with PUT also) When trying to consume the body of the request with .text() we get an empty string. STR: With the attached files as use case. 1. Click on the 'register' button to perform the sw registration (this will reload the same page too) 2. Click on perform a post with payload Expected: This service worker will return the text sent via post, so you should get a text saying: "Response is: This is supposed to be my content" Result: The sw is not able to read the request.text() from the original request, and reads an empty string, so we could see on the screen: "Response is:"

Hei baku, added a test case to try the behavior.
