I have created a component resource that makes a call to

get_caller_identity()

in order to grab the current account id of the locally assumed aws role so it can be used to define an arn in a policy doc: (code snippet has been truncated to save space)

import pulumi_aws as aws

# gets account id
current = aws.get_caller_identity()
account_id = current.account_id

# passes account id when defining policy
self.lambda_policy = aws.iam.RolePolicy(
            "lambdaPolicy",
            role=self.lambda_role.name,
            policy=self.my_lambda.name.apply(
                lambda physical_name: json.dumps(
                    {
                        "Version": "2012-10-17",
                        "Statement": [
                            {
                                "Effect": "Allow",
                                "Action": "logs:CreateLogGroup",
                                "Resource": f"arn:aws:logs:us-east-1:{account_id}:*"

...

When I instantiate this component resource in my project

__main__.py

, it works as expected. However, when I run

pytest

, I get the following error:

________________________________ ERROR collecting tests/test_ip_scan.py _________________________________

    test_args = ip_scan.MonitorAvailableIpsArgs(

    account_id=__ret__.account_id,

Any and all feedback is greatly appreciated!
