vSphere Rest API: Set Guest Customization not working

I need to use the rest API to set metadata but it always failed with 400. Can someone please take a look ? I used base64 to encode the metadata.

Based on the documentation (https://developer.vmware.com/apis/vsphere-automation/latest/vcenter/api/vcenter/vm/vm/guest/customization/put/ ), below is a good payload:

{
"spec": {
"configuration_spec": {
"cloud_config": {
"cloudinit": {
"metadata": "aW5zdGFuY2UtaWQ6IGJpZy1pcC1uZXh0CmxvY2FsLWhvc3RuYW1lOiBiaWctaXAtbmV4dApkc21vZGU6IGxvY2FsCm5ldHdvcms6CiAgdmVyc2lvbjogMgogIGV0aGVybmV0czoKICAjIG9wYXF1ZSBJRCBmb3IgcGh5c2ljYWwgaW50ZXJmYWNlcywgb25seSByZWZlcnJlZCB0byBieSBvdGhlciBzdGFuemFzCiAgICBlbnMxNjA6CiAgICAgIGFkZHJlc3NlczoKICAgICAgICAtIDEwLjE0Ni4xNjguMS8yNAogICAgICBnYXRld2F5NDogMTAuMS4xLjEKICAgICAgbmFtZXNlcnZlcnM6CiAgICAgICAgYWRkcmVzc2VzOiBbMTAuMS4xLjFd"
},
"type": "CLOUDINIT"
}
},
"global_DNS_settings": {},
"interfaces": [
{
"adapter": {
"ipv4": {
"type": "STATIC"
}
}
}
]
}
}

However, when I use curl to send the request, it failed. Below is the request and response .

I suppose you would need to pass proper/complete data to interface and dns if you want to set them.
