    // active. This is scheduled to change in v4.x. When using the middleware
    // we want to call the next function even if the agent is inactive, so
    // until we release v4.x we need a way to tell the captureError function
    // that the callback should be called even if the agent is inactive. This
    // is done by naming the callback `_opbeatMiddleware`.
