the class ProcessFunctionProcessInterceptor method before.

    // Set server marker - server handlers may create a client to call another Thrift server.
    // When this happens, TProtocol interceptors for clients are triggered since technically they're still within THRIFT_SERVER_SCOPE.
    // We set the marker inside server's input protocol to safeguard against such cases.
    Object iprot = args[1];
    // With the addition of TProtocolDecorator, iprot may actually be a wrapper around the actual input protocol
    Object rootInputProtocol = getRootInputProtocol(iprot);
    if (validateInputProtocol(rootInputProtocol)) {
        ((ServerMarkerFlagFieldAccessor) rootInputProtocol)._$PINPOINT$_setServerMarkerFlag(true);
