Running into this error ☝️ . What could be wrong?

Have you tried rerunning with the env var set as suggested? This normally means some promise do not have anything waiting on it. It could be an issue in the Pulumi runtime, but I have not seen any issues related to this recently - so my guess is it’s something in your code. The additional details you get if you enable that env var may help pinpoint the problem.

Here is the leaks from the stackoutput any help would be greatly appreciated. I am stuck with this and it is a blocker. Thanks

I see this - that seems to be the root cause. Did you make any recent changes that might have caused that?

Promise leak detected:
    CONTEXT: transferIsSecret(resource:monitoring-nodes[aws:cloudformation/stack:Stack], tags, Calling [toString] on an [Output<T>] is not supported.
    To get the value of an Output<T> as an Output<string> consider either:
    1: o.apply(v => `prefix${v}suffix`)
    2: pulumi.interpolate `prefix${v}suffix`
    See <https://pulumi.io/help/outputs> for more details.
    This function may throw in a future version of @pulumi/pulumi.)

No, I haven’t. The funny thing is that it works perfectly fine on other stacks. But when I try and do it on this stack it runs into an issue.

Can you share the snippet of code used to create the resource referenced above ( an aws.cloudformation.Stack named monitoring-nodes?). In particular - what is passed into its tags?

I removed the cloudformation for monitoring and I still see the issue.

cc @lemon-spoon-91807 and @microscopic-florist-22719 as I've been talking to them offline about this. One thing we noticed is the use of some tests running during the deployment. That testing framework may well be part of what's triggering this. Is it possible to temporarily disable the tests from running and see if you still hit this?

Absolutely!

@chilly-photographer-60932 let's take this to DM

OK. Thanks

@microscopic-florist-22719 lmk if you need help from me.
