Setting up redundant GCP Connections

I'm trying to create a primary and secondary GCP connection. I created a primary connection, however, when I try to create the secondary connection I get the following response:

[
    {
        "errorCode": "EQ-3142303",
        "errorMessage": "Only Primary connection allowed for this CSP",
        "details": "Given service profile does not allowed redundant connection",
        "correlationId": "null-0000-103912200151-api",
        "additionalInfo": [
            {
                "property": "/redundancy/priority"
            }
        ]
    }
]

However, if I get the service profile details via the API:

https://api.equinix.com/fabric/v4/serviceProfiles/{UUID}

in the "metadata" section there is an attribute "redundantProfileId" which lists the profile Id I was using to try and create a redundant connection. Am I misunderstanding this as it seems that since there is a "redundantProfileId" listed that the profile should support redundant connections?
