Fatal exception: TypeError: proc.send is not a function

Trying to graceful shutdown a server that stops queues and workers before stop and am getting this error:

[exiting] Fatal exception: TypeError: proc.send is not a function

Here is my graceful shutdown script:

export interface OurQueue extends Queue {

    scheduler?: QueueScheduler,
    worker?: Worker
}

const gracefulShutdown = async (queue: OurQueue, server: Server) => {

    const bullConnections = [
        queue,
        queue.worker,
        queue.scheduler
    ];

    for (const conn of bullConnections) {

        try { await conn?.close(); }
        catch (err: any) { server.log(['error'], err); }
    }

};
