'platform.gcp.defaultMachinePlatform.type: Invalid value: "": Machine type do not support Enabled', although both compute and controlPlane are specified valid machine types

    4.19.0-0.nightly-2025-04-02-170034

    Always

    1. "create install-config", and then insert the interested settings (see [1])
    2. "create manifests" (or "create cluster") (see [2])

ERROR failed to fetch Master Machines: failed to load asset "Install Config": failed to create install config: invalid "install-config.yaml" file: platform.gcp.defaultMachinePlatform.type: Invalid value: "": Machine type do not support Enabled. Machine types supporting Enabled: c2d, n2d, c3d 

    "create manifests" (or "create cluster") should succeed, because although the default machine type "n2-standard-4" doesn't support "confidentialCompute: Enabled", both the specified compute[0].platform.gcp.type and controlPlane.platform.gcp.type support "confidentialCompute: Enabled".

    FYI Please see [3] and [4] for how disk type are validated against machine type.
