Getting error 4 when starting the hyperledger caliper benchmark - hyperledger-fabric

Question

I created a functional network with 3 nodes and an orderer using the hyperleger fabric, in which I can carry out the communication between all nodes, executing existing operations in smart contracts. This network does not have TLS validation between nodes. The cryptographic material was created in one of the nodes and distributed among the other nodes in the network.
Now I'm trying to check the performance of the network using the hyperledger caliper. I created the test file, the network file and the other files needed to perform the performance evaluation, however, I am getting Error 4 in return.
Someone could help me, I am stuck on this problem for a few weeks and I don't see how to solve
it.

If necessary, I make the configuration files available to help find the cause of the problem.

Answer 1

From the errors shown above, it looks like a credentials issue.
I would recommend moving up to using the v2 fabric connector that is present in the most recent (0.4.2) Caliper release. It is based on the use of an explicit caliper configuration file that references Fabric Common Connection Profiles. There is a tutorial present in the Caliper documentation that should help you create the required resources, currently accessible at https://hyperledger.github.io/caliper/v0.4.2/fabric-tutorial/tutorials-fabric-existing/
