Serverless Cube.js - No messages published to SNS

Question

Trying to turn a containerized Cube.js deployment into a serverless one. I’m getting Continue wait on every API call, and I notice the cubejsProcess lambda is never invoked. I checked SNS reachability by (successfully) publishing a message to it using the AWS SDK in the cubejs lambda. The cubejsProcess does get invoked with this inserted message. What might be preventing cubejs from publishing messages to SNS?

This is similar to this question, however, connectivity to SNS has been verified in this case.

Answer 1

I'd check IAM permissions to see if the cubejs Lambda's role. Does the role allow making requests to SNS?

Another thing that could be causing the issue is if the cubejs Lambda is in a VPC with no Internet access; calling any AWS API endpoint would fail since they all require an Internet connection.
