How to get the id back after creating aws_lambda.Function?

[rafrafek]

Hello,

I need to access the id value I used to create a lambda function. I need to get the exact same string value. I'm getting Error: Cannot access attribute "id".

How to do it?

from aws_cdk import aws_lambda
from constructs import Construct


class Foo(Construct):
    def __init__(self, scope: Construct, construct_id: str) -> None:
        super().__init__(scope, construct_id)

        functions = [
            self.setup_lambda("foo1"),
            self.setup_lambda("foo2"),
            self.setup_lambda("foo3"),
        ]

        # Expected to print "foo1", "foo2" and "foo3"
        for function in functions:
            print(function.id)  # Error: Cannot access attribute "id"

    def setup_lambda(self, function_id: str) -> aws_lambda.Function:
        function = aws_lambda.Function(
            scope=self,
            id=function_id,
            runtime=aws_lambda.Runtime.PYTHON_3_12,
            code=aws_lambda.Code.from_asset(f"foo/{function_id}"),
            handler=f"{function_id}.handler",
        )
        return function

The answer is simple:

print(function.node.id)
