Link an Alexa Skill to a specific Lambda alias

Question

I'd like to make use of AWS Lambda's versioning and aliases for managing code which is linked to an Alexa Skill.

Therefore, I have two aliases PROD and UAT (pretty much as described in the AWS Documentation).

However - If I try to configure the ARN of one of my aliases (e.g. arn:aws:lambda:eu-west-1:1234567:function:Alexa-Skill:PROD) to be the endpoint for an Alexa skill in the Amazon Developer Console I get the following error:

Error: Please make sure that "Alexa Skills Kit" is selected for the event source type of arn:aws:lambda:eu-west-1:1234567:function:Alexa-Skill:PROD

The unqualified ARN (i.e. arn:aws:lambda:eu-west-1:1234567:function:Alexa-Skill) works fine.

Is this a known limitation of the integration between Alexa Skills Kit and Lambda?

Answer 1

You will need to add the Alexa Skill as the trigger for the Lambda function alias for this to work.
