I am working on creating a cluster on Google cloud via Pulumi on VScode platform and it is written in Typescript but "cluster" is flagging red.

```
import * as pulumi from "@pulumi/pulumi";
import * as gcp from "@pulumi/gcp";

const cluster = new gcp.container.Cluster("cluster", {
    zone: "us-central1-a"
    initialNodeCount: 3,
});

export const clusterId = cluster.id;

```

Please assist on what could be done to aid the successful creation of the cluster using Pulumi with IAC for google cloud. Thanks.
