Paywall validation error

I experienced the “paywall validation error” as some others have mentioned. I checked the network tab in the browser console and still can’t figure it out. It’s related to missing required fields, but can’t make sense of which one from the long field names here:

{
    "code": 7862,
    "errors": [
        {
            "field": "config.base.sticky_footer.stack.components.0.stack.components.0.package.stack.components.0.stack.components.0.stack.components.1.text.color.dark.hex.value",
            "message": "Field required",
            "type": "missing"
        },
        {
            "field": "config.base.sticky_footer.stack.components.0.stack.components.0.package.stack.components.0.stack.components.0.stack.components.2.text.color.dark.hex.value",
            "message": "Field required",
            "type": "missing"
        },
        {
            "field": "config.base.sticky_footer.stack.components.0.stack.components.1.package.stack.background.color.value.light.hex.value",
            "message": "Field required",
            "type": "missing"
        }
    ],
    "message": "Paywall validation failed"
}
