    FunctionStatus functionStatus = null;
    try {
        functionStatus = functionRuntimeManager.getFunctionInstanceStatus(tenant, namespace, functionName, Integer.parseInt(instanceId));
    } catch (Exception e) {
        log.error("Got Exception Getting Status", e);
        FunctionStatus.Builder functionStatusBuilder = FunctionStatus.newBuilder();
        functionStatusBuilder.setRunning(false);
        String functionConfigJson = org.apache.pulsar.functions.utils.Utils.printJson(functionStatusBuilder.build());

    return Response.status(Status.OK).entity(jsonResponse).build();
}
