Remove error Response type check (#731)

* Remove error Response type check

Minimization is impacting type checking in a non-consistent way.
The previous type check works locally,
but not from build artifacts 🤷. We only set `captchaRequired` on
our errors when we want a resubmit with captcha included, so we're safe
keying off that
