question / assist for next guy...using aws cli terminal

[peterkrentel]

This code might be pretty old, learning cdk and things as i work through this ecs workshop.

I can't figure out how to inject the account: and region: into the cdk synth.

So I added the code direct to the file:

https://github.com/aws-containers/ecsdemo-frontend/blob/main/cdk/app.py ln:349

seems like the _env is jacked or just old

For anyone down road wasting a couple hours.
env={
"account": "123456789012", # your AWS Account ID
"region": "us-west-2" # your desired AWS region
}

kept getting

cdk $ cdk synth
jsii.errors.JavaScriptError:
@jsii/kernel.RuntimeError: Error: Cannot retrieve value from context provider vpc-provider since account/region are not specified at the stack level. Configure "env" with an account and region when you define your stack.See https://docs.aws.amazon.com/cdk/latest/guide/environments.html for more details.

The above exception was the direct cause of the following exception:
