It means that if you look at what's returned by
interaction['interaction']
it doesn't contain a key named "link" for you to access. It's an
issue with your data. If it's user-sourced or 3rd-party-sourced
data, you need to test for the case and make sure that you handle it
in a way appropriate to your app ("hey, ninny, you sent a malformed
document" or "hey, our data-provider is a dim bulb"; or this missing
information might be entirely normal, so handle that case). If you
sent it to them and they sent it back tampered, you might want to
sign it and then yell at them if they tamper with bits they shouldn't.
And treat all my dope-slapping terms as bad UX, adjusting
accordingly :-)
