Description:
Protocol: Web / HTTP
Base URL: https://jsonplaceholder.typicode.com This is a public site so MF can
run the script without any issues.

When we setup an asynchronous request and enable RTS -> Preferences -> HTTP -> 'Enable HTTP/2 features', the moment that the Async request is executed for the first time, the log reports many consecutive 'The request to server https://jsonplaceholder.typicode.com/posts" is done with headers', but the body is not sending. This sequence of actions ends with the error: 'Warning -27760: Request "https://jsonplaceholder.typicode.com/posts" failed'

This is tested with VuGen and with Controller.

We ran into this problem in a larger test but could bring it down to this mock-up.

Attached files:
AsyncWithHTTP2Fails.zip Vugen script to demo: you can run this internally also.
AsyncWithHTTP2FailsLog.zip Vugen log file of replay with full logging.

Request:
Please check to see if there is a solution for this or else bring this to the attention of MF Development.
