I’m not reproducing this on my end so far, but out of curiousity, where is 
config.vpc.vpcId
coming from? I see 
vpcConfig
and 
dbConfig
, but no 
config
.
I’d have expected based on your description something like 
vpcId: vpc.vpcId
in the SecurityGroup declaration, since it looks like you’re passing in 
network.vpc
.

I actually have something very close to the example you provided. 
config
is a structure parameter regrouping a lot of different parameters, it includes the 
network.vpc

Can you please tell me what versions are you using for your packages ?
What surprises me most is that by replacing the `vpcId`by a random string the pulumi up command works. Only when using my vpc provided in the parameters it fails
m
Ah! thanks for that. Ok, I have a local repro now. Lemme see.
(Incidentally I’m using the same package versions as you)
Ok so to me, it looks like it’s this line that’s the core problem: 
{ parent: network.vpc }
. Try removing that line (from your 
AubeDatabase
declaration) and running again.
Specifically what that line is saying is that you want your component resource (
AubeDatabase
) to be parented by an 
awsx.ec2.Vpc
resource that’s being passed into (and then parented by) the component you’re creating. This is technically allowed, at least today, and apparently works up to a certain point, but it’s not common practice to use 
parent
in this way; rather, it’s used mainly to parent the resources managed by a component resource (
{ parent: this }
) and that’s about it. I think you’ll find if you switch things up to use 
parent
to associate only the direct children of a component resource, and adjust all other 
parent
references accordingly, the errors will go away. (Alternatively, it looks like you could also change the 
parent
of 
AubeDatabase
to be 
network
, rather than 
network.vpc
, and have that work, too. I do think this qualifies as two kinds of bug, though — one, in the documentation, which makes no mention of this behavior, and two, of the CLI, which should probably warn or fail on this rather than kick out an error you can’t really make sense of.

I thought we might have a bug on this already, but so far, I’m not seeing one. I’ll get one filed if that’s the case and post back here — but do give that a try and let me know if that clears things up for you.
I went ahead and filed this issue to get some better documentation around this: https://github.com/pulumi/pulumi-hugo/issues/2519
r
I did try to make `AubeDatabase`a children of 
network
instead of `network.vpc`and it indeed solved my issue!! I must say a very big THANK YOU for helping me on this. I spent literally a week modifying a lot of things, trying to debug and search all over internet without any success and without having any clue about what's happening. I was starting to consider giving up on Pulumi. You really saved me there. That's very kind of yours to take time to reproduce my bug and help me. I am feeling very grateful towards you! Have a good day 😄!

One thing that confuses me a bit still though is that I can add a `AubeVPN`that is a child of `network.vpc`without having any trouble.
Copy code
const cloudflareConfig = new Config("cloudflare-config");
const vpn = new AubeVpn(
    name,
    {
        vpc: network.vpc,
        cidr: vpcNetworkCidr,
        cloudflare: {
            zoneId: cloudflareConfig.require("zoneId"),
        },
    },
    { parent: network.vpc }
);
Ideally I would like my `AubeDatabase`to be a child of 
network.vpc
instead of 
network
because if the VPC disappear, the Database should logically as well. Why can't the `AubeDatabase`be a child of 
network.vpc
? I can't see any circular dependency. If it works for my `AubeVpn`then it should as well for the Database
m
Sorry for the delayed response — yeah, I noticed as well that it wasn’t until adding the second reference to 
network
from within the Database component that the promise errors began. One reference, no problem — two, and the compilation fails. I’m afraid I don’t have a good answer for you as to the “why”, unfortunately; something about this particular component (
awsx.ec2.Vpc
) seems to be the root cause, but someone with deeper knowledge of that component will need to investigate. I’ll file another issue once I have a good repro and can explain the behavior. Will tag you on that so you have it as well.
