Error when deploying--invalid subnets

[mlfarrelly]

Really enjoying the book, but when I try to deploy, I keep getting this error message:

Error message:

An error occurred: RDSSubnetGroup - Some input subnets in :[subnet-04cb33f4001924f59, subnet-084fb5fd9987a0cf7] are invalid. (Service: AmazonRDS; Status Code: 400; Error Code: InvalidParameterValue; Request ID: 60ac3262-5b4c-43b8-b924-7043d6299e62).

I've tried manually creating new VPCs and subnets per the AWS docs, but nothing is working for me.

Any thoughts? Thanks!

Hi @mwebdev1

Thanks for this, I'll take a look. Which chapter's code were you seeing this error?

Chapter 2. I'm getting the error when I try to deploy with a yml file based off of yours:

`functions: createuser: handler: api/handlers.createuser events: - http: path: /createuser method: post cors: true getuser: handler: api/handlers.getuser events: - http: path: /getuser/{id} method: get cors: true
