Error using framework hyperledger caliper - testing

Question

I have two test tests, one reading and one writing on the blockchain. I'm getting two different errors, one at the start of the test and one at the writing test. The reading test is working normally without problems.
Initial error:

I kindly ask for any tips so that I can solve these problems and follow the development.

Answer 1

From the network file you posted a couple of points
you can't define any nodes in it (for example you've added orderers). They are ignored
you've specified that your connection profile is a dynamic profile by setting discover to true in your network file, this means it will use discovery to determine the network topology and may not use the nodes you have explicitly defined in your connection profile. If you want to be explicit in your connection profile (and thus define a static connection profile) like you have in your above example, you should set discover to false, which hopefully will solve your problem.
As a side note, if you use discovery then the node-sdk (used by caliper) and caliper by default converts all discovered node hosts to localhost, which is why you see it trying to contact localhost. To disable this see Runtime settings in https://hyperledger.github.io/caliper/v0.4.2/fabric-config/new/

Answer 2

The issue was in the connection file.
The old file was:
---
name: fabric
version: 2.0.0
client:
organization: Org1
connection:
timeout:
peer:
endorser: '300'
orderer: '10000'
organizations:
Org1:
mspid: Org1MSP
peers:
- peer0.org1.example.com
certificateAuthorities:
- ca.org1.example.com
orderers:
orderer.example.com:
url: grpc://192.169.0.9:7050
grpcOptions:
ssl-target-name-override: orderer.example.com
peers:
peer0.org1.example.com:
url: grpc://192.169.0.7:7051
tlsCACerts:
path: crypto-config/peerOrganizations/org1.example.com/tlsca/tlsca.org1.example.com-cert.pem
grpcOptions:
ssl-target-name-override: peer0.org1.example.com
certificateAuthorities:
ca.org1.example.com:
url: http://192.169.0.7:7054
caName: ca-org1
tlsCACerts:
path: crypto-config/peerOrganizations/org1.example.com/tlsca/tlsca.org1.example.com-cert.pem
httpOptions:
verify: false
The new connection file that I created is this:
---
name: fabric
description: "Sample connection profile for documentation topic"
version: 2.0.0
channels:
channelall:
orderers:
- orderer.example.com
peers:

grpcOptions:

peers:

grpcOptions:

request-timeout: 120001
peer0.org2.example.com:
url: grpc://192.169.0.10:7051
grpcOptions:
ssl-target-name-override: peer0.org2.example.com
request-timeout: 120001
peer0.org3.example.com:
url: grpc://192.169.0.11:7051
grpcOptions:
ssl-target-name-override: peer0.org3.example.com
request-timeout: 120001
With all information about peers and orderers.
Thanks everybody for the help.
