My Lambda takes in an SQS message containing an ID and address. It parses out those fields, and updates the record associated with that ID in a dynamo table.

The parameters for this update contain the following logic

1.Where the record has a id equal to the ID sent by SQS

2.And where the SortKey has a value equal to “null” (Note that null is specifically a String with a value of “null”)

3.Update the address field with the new address

I'm seeing the following issues with this function

1. The function is not updating the DynamoDB instance

2. I am not receiving any kind of feedback from the update call. Looking over the code there are several console.logs that should execute but are not. See the Try,Catch,Finally block after the update. Looking at the logs you can see that these do not output to the console. Something is very wrong here. The finally not executing looks like undefined behavior, my only guess is that the call to dynamodb is not being awaited

I also need to implement the following functionality. This is bonus points, if you have an idea of how to do it please feel free to comment!

Right now the update will only change the fieldname of address from one value to another. Instead, I need the record to contain a set of addresses associated with that record. To do this we need to implement the following logic

If a set of addresses does not exist on the record, create a set with the address as the only element If a set does exist on the student record, update that set with the address. Duplicate addresses should not be added

The code for this function is below. I’ve also attached the most recent CloudWatch log for this function, and the record I am trying to update (the address field on the record was added manually). You’ll notice that we aren’t getting any console.logs after console.log("starting upload"), and the promise has a state “PENDING” when it is examined. We also don’t get any feedback from the dynamodb update. Right now the function is not updating the record, and not giving me any feedback for why it is failing to do so.
