I've got Caliper configured as a subtree of my custom Fabric blockchain. I have it configured correctly in order to connect the network and am running a small set of tests at the moment. The arguments I'm providing are absolutely correct in terms of the custom chaincode being run, but whenever I try to create a transaction via Caliper I get the error:
Failed to perform submit transaction [CreateAsset] using arguments [<ARGS>], with error: TypeError: Cannot read property 'status' of undefined
Anybody encountered this before with Caliper V0.4.2? It's interfacing with a Fabric 2.3.3 instance on local machine via Kubernetes, with the latest SDK bound.
The error occurs on line 237 of transactions.js inside the node_module fabric-network, where there is a strict property comparison on a commit object.
Also it's worth noting that the querying part of my test rounds is yielding expected results... none of those assets get created due to the error thrown, and when querying for a given asset an error like so occurs:
Failed to perform query transaction [ReadAsset] using arguments [<ID>], with error: Error: error in simulation: transaction returned with failure: Error: The asset <ID> does not exist
The closest thing I've been able to find is this ~2 year old issue which isn't exactly what I'm facing but it's the same sort of error at least... any help or pointers would be greatly appreciated because I'm struggling to glean useful information. (Link: https://github.com/hyperledger/caliper/issues/727)
The issue was due to the host names being converted to localhost when you want to work anything except a network running locally via docker. You need to launch caliper with the following extra option
--caliper-fabric-gateway-localhost false
I have assets whose state get updated and I want get history of that asset with previous_hash and current Block_hash. I am using CouchDB as State DB of Hyperledger Fabric.
I tried fabcar example function 'getHistoryForAsset' but it can give me only TxID but I need Block hash with this.
Can anybody help me how can we do it.
Thanks
Using the transaction ID you can call (evaluate) the GetBlockByTxID transaction function on the system qscc chaincode to get the block that contained that transaction. It expects a transaction ID as an argument and returns a common.Block protobuf response payload.
https://github.com/hyperledger/fabric-protos/blob/f44816d6f621f1f7615cb4fc65643791eb6d8ce6/common/common.proto#L142
Note that a block only contains the hash of the previous block, not the hash of itself.
I want to create a wallet for new rest api server, but whenever I call code to generate new Wallet I'm getting error like
"Decoding SignatureHeader failed: Error illegal buffer ..."
Here is screen shot of my code, it is taken from virtual machine
I'm using hyperledger fabric 2.2 and run under the fabric-samples/test-network
I was clone this HyperledgerFabroc
Here is also print screen of the error:
I would appreciate if someone can navigate me how to manage successfully to create a wallet ?
Your error looks to be occurring within a chaincode transaction function. You should not be using the client SDK to do a transaction invocation from within chaincode. Instead look to use the invokeChaincode function on the stub:

I having issues with entity framework on Azure Database, I can open up the models and update the database entities but when I try to run the application the first data call get error Entity Framework is throwing an error “Unable to evaluate the expression. Operation not supported. Unknown error: 0x80070057.”
I'm thinking if I can open the model up and update the entities i have the correct permissions.
I'm not getting the same issues when running localhost with localhost database.
Thanks
When I Create the azure database with Entity Framework model first pattern, then the creation works. But when I want to save the database I get the following error:
"Tables without a clustered index are not supported in this version of SQL Server. Please create a clustered index and try again."
I updated entity Framework to Version 6.1.2. But still get the same eroor. Do you have any idea?
