I am trying to create private data on Fabric version 1.2.0.

I have created the collections configuration file for storing private data.

[

 "name": "collectionData",
 "policy": "OR('Org1MSP.member','Org2MSP.member')",
 "requiredPeerCount": 0,
 "maxPeerCount": 3,
 "blockToLive":1000000,
 "memberOnlyRead": true

]

I have instantiated the chaincode using --collections-config flag.I have provided the configuration file correctly and successfully created the network.

I have developed the chaincode using nodejs.

 console.log("************************************");
 console.log("Private Data Testing");
 let sample = "test";
 await stub.putPrivateData("collectionData",transactionId,sample.toString());
 let response = await stub.getPrivateData("collectionData",transactionId);
 console.log("Response",response.toString());

I am doing the operations on behalf of Org1MSP.But I didn't get any response.It returns null while fetching the private details.

Could someone help me to resolve the issue?

  try (where Key1 is your key) - await stub.putPrivateData("collectionData","Key1",Buffer.from(sample.toString())); then let response = await stub.getPrivateData('collectionData',"Key1"); (not sure if you're using transactionId as a key in your scenario..) toString should default to utf8

  ps. You may be also be aware that GetPrivateData doesn't read data from the private writeset, which has not been committed to the collection. In other words, GetPrivateData doesn't consider data modified by `PutPrivateData - that has not been committed.
