@szmarczak @sindresorhus please comment this (very) kludgy fix.

In short, .buffer(), .json() and .text() shortcuts consume the body Buffer bound to the initial asPromise() call and cannot "see" the other body bound to the asPromise() which is called during the afterResponse hook.

There is very likely a cleaner way to handle this issue.

@szmarczak here is a cleaner fix (type casting is somewhat ugly though)

If you don't mind waiting until I finish up the Rewrite PR, it will be much easier to look into this later...

[PopGoesTheWza]

Sure.

[sindresorhus]

This can continue now. #1051 was merged.

[PopGoesTheWza]

Let me now if and how I may assist
