Hey guys.. wondering why my PR had to be reverted: https://github.com/pulumi/pulumi-eks/pull/190 - @breezy-hamburger-69619 or @white-balloon-205 ?

There were apparently two breaks when this ran fully in CI: 1. https://travis-ci.com/pulumi/pulumi-eks/builds/117566528#L1432 (fixed by https://github.com/pulumi/pulumi-eks/pull/189) 2. https://travis-ci.com/pulumi/pulumi-eks/builds/117576992#L1423 (not fixed, instead reverted)

Think I found the issue. I added this call:

instanceProfile = aws.iam.InstanceProfile.get(`${name}-instanceProfile`, instanceProfileName, undefined, { parent: parent });

which should not require a role argument, since its only looking up an existing instance profile. But it seems to invoke a "new" on InstanceProfile:

66     /**
 67      * Get an existing InstanceProfile resource's state with the given name, ID, and optional extra
 68      * properties used to qualify the lookup.
 69      *
 70      * @param name The _unique_ name of the resulting resource.
 71      * @param id The _unique_ provider ID of the resource to lookup.
 72      * @param state Any extra arguments used during the lookup.
 73      */
 74     static get(name, id, state, opts) {
 75         return new InstanceProfile(name, state, Object.assign({}, opts, { id: id }));
 76     }

If I was to guess, it seems like perhaps

instanceProfileName

is undefined here? That could lead to this error from this line I believe.

Think I found the issue. Pushed a commit.
