how to define additional packages in the serverless yaml?

[sarfrazhooda]

I would like to include uuid package that I am referring in API component. Is there a way to define layers? and if yes how do you do that in serverless yaml?

You can configure layers with the layers input:

inputs:
  layers:
    - aws:arn:layer # arn of the layer
