can you not do this within

app.setDefaultFunctionProps()

?

layers: [
      lambda.LayerVersion.fromLayerVersionArn(
        app,
        'KnexLayer',
        process.env.KNEX_LAYER_ARN
      ),
    ],

I’m getting: `Error: Import at 'KnexLayer' should be created in the scope of a Stack, but no Stack found`why have a

layers

array on that method then?

You can do this if you're inside a stack and pass the stack as the first arg to the layer

ahh I see

You shouldn't have a problem creating that in a base stack and setting that. It should work

so I suppose the core stack can import the layer, then pass that into the other stack constructors

I don't think you even need to pass it to other stack constructors unless you're referencing it

well, I need every single Lambda function to include it

This maybe is a bit unclear but if you do

app.setDefaultFunctionProps

in one stack it applies to all functions everywhere

I thought we talked about this before, how

app.setDefaultFunctionProps

is app-wide, and can’t be set on a per-stack basis ?

It's the opposite problem, you can't set defaults for just one stack

ok..bear with me. so the situations I can call

app.setDefaultFunctionProps

are: 1. just once, at app level 2. for all stacks, and it must be all stacks, not 1/3 or 2/3

Not exactly for 2

right.. ok. but you can’t define global

layers

at the app level. that has to be in a stack. but if I define that in my first stack, it should be available for all stacks & all funcs?

In this case you're actually doing 2 things 1. Creating a layer resource 2. setting global defaults It has to be done within a stack because of #1

ok.. whew. thanks 😄
