sam-beta-cdk raises an error without any additional context

See original GitHub issue

Description:

sam-beta-cdk raises an error when trying to start-api or invoke locally. I’m hoping I don’t have to post the entire CDK stack template here because it is large.

Steps to reproduce:

download and install: brew install aws-sam-cli-beta-cdk (osx)
run sam-beta-cdk local start-api

Observed result:

Not sure why, but this workaround at least allows you to continue using sam-beta-cdk:

"@aws-cdk/core:newStyleStackSynthesis": false

SAM CLI’s CDK support went into GA yesterday with some changes. Now sam-cli won’t run cdk but user will have to run and provide the path. This should solve this problem. Please let us know if you have more questions. Please find more details here
