env parameter of cdk.Stack constructor seems to be ignored

[dhx-mike-palandra]

Describe the bug
env parameter of cdk.Stack constructor seems to be ignored. Apologies if I overlooked something obvious.

To Reproduce

1. Initialize a new python CDK project
   cdk init --language python

2. ./cdk_test/cdk_test_stack.py: initialize any construct/resource in the sample stack class; e.g.
   sns.Topic(self, 'CdkTestTopic')

3. app.py: initialize the stack with an explicit region that differs from your default; e.g.

app = cdk.App()
env = cdk.Environment(region='us-east-2')
stack = CdkTestStack(app, 'my-cdk-test', env=env)

Expected behavior
Relevant cdk commands that interact with CloudFormation (e.g., diff, deploy, destroy, etc.) should operate on the region specified above in app.py. In my case, they did not.

Version:

• OS: cpe:/o:fedoraproject:fedora:30
• Programming Language: Python 3.7.3
• CDK Version: 0.34.0 (build 523807c)

I think this is discussed in #2866 - by the way, a temporary fix should be already present (line 515) here) ... but I didn't understand exactly why it doesn't work 🤔

Hi @dhx-mike-palandra!

It looks like @made2591 linked a duplicate issue that has since been resolved.
Please confirm if this fixed your problem so we can either close this issue, or readdress the problem.

Thanks!

[dhx-mike-palandra]

Thanks for following up. I tested again with the latest CDK release:

$ cdk --version
0.36.0 (build 6d38487)

Unfortunately, the issue still persists; i.e. despite an explicit region specification of "us-east-2", issuing "cdk deploy" creates a stack in my default region (which is not us-east-2).

Can you please share some code for a minimal repro?

[eladb]

Oh, just saw that you provided one... Are you propagating kwargs from your stack to the base Stack?

[dhx-mike-palandra]

No; I was not. I just corrected that and tried again, and the stack indeed is created in us-east-2. Sorry for not catching that earlier. Thanks for your advice. Take care.

No worries, just made the same mistake myself in a little python app I am working on :-)

Just for future googlers - I just bumped into this on CDK 2.8. I was referencing the region/account passed in via env as self.env.region in my stack. Turns out that you need to reference them as self.region! Took me a few minutes to work out, doh!
