I use webhooks fulfillment for my responses, and my FindIntent and LocateIntent work perfectly fine. However, I added InstructIntent as a followup intent to FindIntent, and it just doesn't work. I get the following errors in my log when I trigger InstructIntent:

This is after my get call works perfectly fine for my main intent (FindIntent) and it correctly identifies and sets the parameters in find(agent). Any idea what could be going wrong? I tried changing instruct(agent) to
function instruct(agent) {
console.log(agent.get.context('FindIntent-followup').parameters.area);
console.log(agent.get.context('FindIntent-followup').parameters.location);
}
and I got the exact same error trace, even though I removed the webhooks call, and nothing added to the log. The context name is correct as well. Any idea what might be going wrong?
