Yes, it does. Thanks Bill. I guess my confusion is because there doesn’t seem to be any mention in the docs that “custom” is a keyword. My assumption was that i could choose whatever keys i wanted.
If you need to know the list of all available properties in serverless.yml when the provider is set to aws. Please go through this document Serverless.ym Reference
Interesting part is, custom is not in the list. Seems the document need be updated.
