通过java版sdk调用智能合约向Fabric提交交易出现异常

是在程序中通过java版的Fabric-sdk调用部署在远程主机上的智能合约执行相关的业务逻辑,但在执行过程中出现异常信息,导致交易请求没有提交到Fabric的peer节点上,具体异常信息如下:

 17:16:06 [http-bio-8080-exec-5] ERROR org.hyperledger.fabric.sdk.Channel - Sending proposal to peer0.org0.example.com failed because of: gRPC failure=Status{code=UNKNOWN, description=chaincode error (status: 500, message: Failed to unmarshal section -), cause=null}

面对这个问题没有什么头绪,不知道是哪里出了问题,求问Fabric方面的大神能否给帮忙解释一下,这个异常是因为什么问题导致的!!!不胜感激!!!
