It continues to ask me for my email even though it said

Is this error a known issue? Is it something that can safely be ignored? Seeing this error made me think that Jimmy John's has changed their site and that maybe the code needs to be changed, which is why I'm reporting this.

FWIW, here's some information about my system:

$ node -v
v0.10.35
$ uname -srpo
