hi everyone, i'm kicking the tires with pulumi-cdk and I'm running into an issue with what appears to the

Vpc.fromLookup

method. Anyone else bump into this problem? I have an existing VPC that I want to use but Pulumi is erroring out and is instead using a placeholder VPC reference (vpc-12345)

Code:

    constructor(id: string, options?: pulumicdk.StackOptions) {

        });

                    ),
                },
            }
        );

        this.clusterArn = this.asOutput(service.cluster.clusterArn);
        this.serviceArn = this.asOutput(service.service.serviceArn);

        this.synth();
    }
}

new FargateStack("FargateStack", {
    props: {
        env: {
            region: "us-west-2",
            account: "1234567890",
        },
    },
});

Were you able to resolve this? I just tried this myself, and I was able to find a VPC with what looks like the same code using an ID I know exists.

It's quite odd because the exact same code works with CDK and I even tried copying over the

cdk.context.json

that it generated to the Pulumi project and it didn't work so something must be preventing these context lookups. But as a workaround, the

fromVpcAttributes

works but it's not nearly as convenient as

fromLookup

. I also suspect that other modules that have their own

fromLookup

method might fail for the same reasons
