Possible data type discrepancy for `gcp.compute.BackendService`

What happened?

While using our doc examples, it seems like there's a data type discrepancy for the healthChecks property.

Right now, the healthChecks property is of type pulumi.Input<string> but this doesn't seem to be right according to upstream TF provider doc or the Google API resource definition.

Steps to reproduce

Use the code below

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

export = async () => {

    const defaultHttpHealthCheck = new gcp.compute.HttpHealthCheck("defaulthttphealthcheck", {
        requestPath: "/",
        checkIntervalSec: 1,
        timeoutSec: 1,
    });

    const defaultBackendService = new gcp.compute.BackendService("defaultBackendService", {
        healthChecks: [defaultHttpHealthCheck.id],
        enableCdn: true,
        cdnPolicy: {
            cacheMode: "CACHE_ALL_STATIC",
            defaultTtl: 3600,
            clientTtl: 7200,
            maxTtl: 10800,
            negativeCaching: true,
            signedUrlCacheMaxAgeSec: 7200,
        },
    });

    return {

    }
}

Expected Behavior

The code should pass vscode linting
The code should deploy correctly

Actual Behavior

The code fails to pass linting with the error Type 'Output<string>[]' is not assignable to type 'Input<string> | undefined'.ts(2322)
The code fails to deploy
I'm unable to provide more than one health check if I remove the []

Additional context

Removing the [] as shown below allows the deployment to complete.

...
    const defaultBackendService = new gcp.compute.BackendService("defaultbackendservice", {
        healthChecks: defaultHttpHealthCheck.id,
        enableCdn: true,
