In the Pulumi webpage, the path is: '<https://app.pulumi.com/camfoo|camfoo> / <https://app.pulumi.com/camfoo/proj|proj> / <https://app.pulumi.com/camfoo/proj/dev|dev>'

The pulumi.yaml contains:
```name: proj
runtime: go
description: A minimal Go Pulumi program```

If I had to guess, it doesn’t like that the last parameter is `nil` for NewKubernetesCluster, but I’m not sure of the top of my head.

<@U0220CGL4P5> is `pulumi up` even affected by that third parameter in my code, the call to `digitalocean.NewKubernetesCluster(ctx, "proj", nil)` ????? <@UCWG26BH7>

`pulumi up` will execute your pulumi program, so if there is an error in it, it will return that error.

Whether that error comes from there - I am not sure.

<@U0220CGL4P5>, yes that is helping, with the right struct, it now complains about missing members. :slightly_smiling_face:
