Hi All, I’m attempting to create an EKS cluster with managed node groups but I’m receiving the below error. Has anyone seen this before or know how I can get around it? I’d appreciate any help I can get on this.

What does your code for provisioning the cluster look like?
It looks to me like one of the outputs that you're trying to 
map
over is undefined

hmm nothing obvious jumping out at me. I would check that all the outputs you're passing in resolve to what you expect. A handy function for that is:
Copy code
def pdebug(output):
    """
    Print debugging for Pulumi outputs.

    The best way to use this function is to add it to an apply chain. So given an output
    like this:

        output = namespace.metadata.apply(lambda metadata: metadata.name)

    You can use pdebug to debug it at various points like this:

        output = (
            namespace.metadata
            .apply(pdebug)
            .apply(lambda metadata: metadata.name)
            .apply(pdebug)
        )

    This will print the metadata and the result after the name has been extracted.
    """
    <http://pulumi.log.info|pulumi.log.info>(
        json.dumps(
            output,
            indent=4,
        )
    )
    return output
the problem is specifically with the managed node group, I wonder if making 
prod_eks_cluster
the parent could be causing some weird issues as well.
If you look at the relevant source code https://github.com/pulumi/pulumi-eks/blob/master/nodejs/eks/nodegroup.ts the only thing they are calling 
map
on is the 
extraNodeSecurityGroups
and 
roles
which I think corresponds to 
instance_roles
