"Missing 'proposalResponses' parameter in transaction request"

JessKXWL commented 2 years ago

I recently started learning fabric and wrote a small demo, but there were errors when uploading data using postman. When I upload the following data, the code will not make mistakes.But when the data I upload is 15M, an error will be reported,"Missing 'proposalResponses' parameter in transaction request"。here is the data

{
    "identifier": "client0_to_rsu4_epoch1",
    "data": {
        "enc_vectors": {
            "conv1.weight": "conv1.weightxxxxxxxxxxx",
            "conv1.bias": "conv1.biasxxxxx",
            "conv2.weight": "conv2.weightxxx",
            "conv2.bias": "conv2.biasxxxxxx",
            "fc1.weight": "fc1.weightxxxxx",
            "fc1.bias": "fc1.biasxxxx",
            "fc2.weight": "fc2.weightxxxxxxx",
            "fc2.bias": "fc2.biasxxxx"
        },
        "dec_aes_key": "chBXLZA03PXYzs43UArhGfGsSn7TACdldFIqYPTO3/FjS73h50IX4RSoALE13fqkROEray0lsLiShIN/48exerGDEaL0BN6O0gGpq55WwNtRUqrsOvGzwisFLJVGK3d5nCyo+Hw8QwjO4fwfQs2ynpeubP1+Zr/TIx09p4NDUHM=",
        "loss_slice": 0.10846090443590854
    }
}

The following is the data displayed in the docker log

I wonder if this problem occurs because the uploaded data is too large.

I tried to change PreferredMaxBytes from 512KB to 15MB, but it didn't work.

Is there any way for me to upload such large data?

@JessKXWL Dear friends, how did you deal this problem later?

@JessKXWL Dear friends, how did you deal this problem later?

I didn't solve this problem, but later I tried to find out the limit. It's OK to upload data below 4M. The maximum data transmitted by the gossip protocol is also 4M, so I think it's related to the gossip protocol. However, there will still be errors when modifying the maximum data transmitted by the gossip protocol. It may be that I changed the wrong place

@JessKXWL : Check the network.json, verify the peer endpoints configured are correct or not.

我的问题跟你的问题一样。但我是获取数据时报的这个错误。

JessKXWL commented 11 months ago

时间太久了，我有点不太记得了，我印象中是因为grpc协议传输的数据设置为了4M，而我传输的数据远超过4M，所以出错了。在这个代码里面有地方可以设置GRPC协议传输数据大小，不过我当时设置的时候可能没找对地方，没设置成功。

确实是这样，是由于grpc协议数据量的关系，貌似是在一个配置文件里修改，数额修改地大些，也别太大

请问是在network.json文件里面改吗？

  "orderers": {
    "orderer.example.com": {
      "url": "192.168.227.128:7050",
      "grpcOptions": {
        "grpc.ssl_target_name_override": "orderer.example.com",
        "grpc-max-send-message-length": -1 // 无限制
      },
      "tlsCACerts": {
        "path": "./crypto-config/ordererOrganizations/example.com/tlsca/tlsca.example.com-cert.pem"
      }
    }
  },

但是改了后，重新启动程序还是报这个错误。
