Failed to create user identity: "contract not defined: gi.contracts/identity".

[taoeffect]

Problem

Very weird, sometimes this happens when trying to sign up a user.

Once it even happened where it succeeded in [Container Tab 1], but failed in [Container Tab 2] and [Container Tab 3] when joining u2 and u3 to a group!

EDIT: Another time, I successfully created u1 in Browser 1, u2 in Browser 2, but when I tried u3 in Browser 3 it failed from that point on. Even attempting to create u3 in Browsers 1 or 2 (in different containers) failed too! It seems like once this error happens once, it keeps happening until after grunt dev is restarted.

I'm forced to restart grunt dev to fix.

Solution

Find out what's going on and fix.
