Hi @Jaskerv, I've just successfully created a default cluster (using your code sample above) and found no issues creating the cluster. Please could you let me know which version of the aws provider you are using in this project? Could you also confirm which resouce is throwing the error, and if there are any stack traces available? Thanks!

I've tried it with the node v18 and v14. Still the same issue.

Providers:

        "@pulumi/aws": "^5.10.0",
        "@pulumi/awsx": "^0.40.0",
        "@pulumi/eks": "^0.41.0",
        "@pulumi/kubernetes": "^3.0.0",
        "@pulumi/kubernetesx": "^0.1.5",
        "@pulumi/pulumi": "^3.0.0"

Running with verbose logging:

❯ pulumi up -v 9

I've also updated everything. Same issue :(

Thanks for the stack trace - that's super helpful. It looks like the command kubectl version --output=json is returning something that is not JSON. Executing that command on your machine will likely highlight what the issue is.

[roothorp]

I'll keep this open until we can determine what's causing the parse to fail.

I just had the same issue. What solved it for me was to select a context for kubectl (I had no selected context the when the error accoured). Maybe this will help :)

Yeah this happened to me as well because of a bad ~/.kube/config even though the associated file was nothing to do with my pulumi stack. Removing that file fixed it.
