[SOLVED] Spring XD custom class type for processor input

I wrote a proccessor module that gets a String payload and return results as LogFileTuple type. this module works good.
I wrote another module that gets LogFileTuple as input. but when deploying stream as: Source | Module1 | Module2 | Sink get MessageDeliveryException.

My transfor method:

public Event transform(LogFileTuple payload) {
    if (payload == null) {
      return null;
    }

    try {
      Event event = logParser.parse(payload);
      if (event != null) {
        return event;
      } else {
        logger.warn("LogParser result is null: {}.", payload);
        return null;
      }
    } catch (Exception e) {
      logger.warn("Cannot parse logFileTuple: {}.", payload, e);
      return null;
    }
  }

my xml config for Module2 is:

<int:channel id="input" datatype="com.company.threatanalyzer.core.commons.tuple.LogFileTuple"/>

<int:transformer input-channel="input" output-channel="output">
    <beans:bean class="com.company.threatanalyzer.xd.plugin.XdLogParser" />
</int:transformer>

<int:channel id="output"/>

I get this exception:

Caused by: org.springframework.messaging.MessageDeliveryException: Channel 'input' expected one of the following datataypes [class com.company.threatanalyzer.core.commons.tuple.LogFileTuple], but received [class com.company.threatanalyzer.core.commons.tuple.LogFileTuple]
