Hi, can you provide the request body here for us?

mutation TcpProxyCreate($input:TCPProxyCreateInput!) {
    tcpProxyCreate(input: $input) {
        applicationPort
        createdAt
        deletedAt
        domain
        environmentId
        id
        proxyPort
        serviceId
        updatedAt
    }
}

Input:

{
    "input":{
        "applicationPort":3306,
        "environmentId":"",
        "serviceId":""


    }
}

To be clear, environmentId and serviceId is not empty when you're running the actual call?

How many times are you calling this with each environment/service?

We call this only once during the service creation process, ensuring that both environmentId and serviceId are populated before making the actual call.

I can't speak to why you could be getting the Problem processing request error, but would you mind giving us wide overview of what you are trying to accomplish here, perhaps there may be a better solution here.
