Vue 2 component does not post s3 info

[jameswagoner]

bucket: ""
content_type: "image/jpeg"
expires: ""
visibility: ""

That is what is in the payload when s3 support (vapor) and gives validation error

{
    "message": "The given data was invalid.",
    "errors": {
        "key": [
            "The key field is required."
        ],
        "bucket": [
            "The bucket field is required."
        ],
        "name": [
            "The name field is required."
        ],
        "size": [
            "The size field is required."
        ]
    }
}

I have s3 setup correctly, was doing uploads with livewire but moving away from livewire, so not sure what config is missing. Docs don't seem to call out anything other than following laravel s3 instructions.
