At what point does accessing the request become unsafe?

I am running into the error Using uWS.HttpRequest past its request handler return is forbidden (it is stack allocated), and am having some trouble figuring out when access to the request is disallowed.

Right now, I am actually getting the error while still in the request handler. I am not completely sure, but it seems like I lose access to the request once I call res.onData, but that may just be a coincidence.

I modified the JsonPost example to use a promise rather than the callback pattern and was able to reproduce it -- here is gist that demonstrates the behavior that I am experiencing

Also I am using v15.5 currently and node 10.14.1.

Await is technically a return. The async function is technically split in two actual functions; the first part up until await and the continuation is technically its own separate function.

Easiest rule of thumb is to just read all headers you need, at the top of the function:

let userAgent = req.getHeader('user-agent');

Then forget about the req and only use userAgent.
