I’m deploying an SST app for the first time using Seed. The app deploys fine using

sst deploy

but when using Seed it fails with lots of missing aws-cdk dependencies. Here’s some of them

SST: 0.13.0
CDK: 1.98.0

Anyone know what could be causing this?

Let me take a look at the build.

It looks like downgrading npm to v6 has done the trick, thanks for the pointer.
