Code review help: Lambda function to call Amazon Connect API for outbound calling

Question

(I'm a rank beginner - looking for some pointers/guidance from the gurus here)

I am trying to write a Lambda to call a Phone number and initiate a simple Connect call-flow. Here is the code I am trying and errors I am getting. Any suggestions?

Sample Lambda Code for calling Connect API

I am using a Default Outbound Callflow (AWS built in callflow) configured for outbound call

Here is the error I am getting when I do a standalone Lambda test

Response:
null

Request ID:
"e83a6066-f670-11e8-afa4-47dc77991dc5"

Your error (ContactNotFoundException) is coming from the connect.stopContact call

If you check connect:StopContact you can see that a ContactNotFoundException occurs when the contactId you've specified can't be found. Which means either:

You have the wrong params2.ContactId (i.e. you're trying to stop a contact that does not exist).
You have the wrong params2.InstanceId which means that even if you have the right contact id, they don't exist on this instance.

I suspect you've got contactId wrong. If we take a look at connect:StartOutboundVoiceContact you'll see that it returns the value of ContactId. I suspect that you should be capturing this value, and then using it in your params2 object, rather than the hardcoded value.
