Thanks a lot David for your response. So digging deeper into the logs, we found that peer was returning below error: [chaincode] BuildQueryResponse -> ERRO Failed to get query result from iterator [ch

Hi, While trying to get data from hyperledger fabric, we are getting following error at client side "Error While Query ERROR:Error: error getting results for query response error: QUERY_STATE_NEXT fai

The query appears to be a JSON find query. These queries will be slow or time out if they do not utilize a well designed index against the JSON data. See the CouchDB tutorial for more details: https:/

when my chaincode wants to write to the implicit private data collection, I need to get the local MSPID where the chaincode is deployed. What is a good way to get it? check the ENV of CORE_PEER_LOCALM

This, I believe, will be a mismatch of versions on the `build.gradle` file; Check the version of the 'shadowJar' plugin used - in some examples there was an older version of this that was for previous

Hello, Even with v2.0 it is possible to use the prior chaincode lifecycle process. You would need to make changes in configtx.yaml file for capabilities to be of the previous version instead of v2.0.

Hi Prasanth, Is it different from using a composite key https://github.com/hyperledger/fabric-samples/blob/master/chaincode/marbles02_private/go/marbles_chaincode_private.go#L276 ? One addition to abo

Well, if you want to do a write you would use a PutState. In theory you can also persist to the Blockchain, transactions that have an empty write set, which are basically queries, but I doubt it's wid

#fabric #fabric-chaincode

Oh yes, Write will only happen when "Create", "Update" and "Delete". In that case. But still, User will probably perform Query before calling Create or Update, so Query still won't know if it is a wri

Hi Senthil, You are right to some extent. My first inspiration is from the composite keys. In fact, the first set of ideas involved just having composite key as index for each and every field in the s
