Hello,

I am getting the following error when running the application:

I get no issues when running ./build_mac.sh.

The application just hangs after I ‘try to buy insurance for a bike’ on this step: https://github.com/IBM/build-blockchain-insurance-app/blob/master/images/Picture3.png

Docker version 18.03.1-ce, build 9ee9f40 docker-compose version 1.21.2, build a133471 npm 5.6.0 node v8.11.3 Python 2.7.13

I have tried multiple checkouts and reinstalling dependencies. I also get the same issue on Ubuntu 18.04.

Before solving these issues, please use ./clean.sh first to clean your docker containers.

Join Peer Issue

Symptoms: Stuck inJoining peers to the default channel. Timeout: error: [Peer.js]: sendProposal - timed out after:45000 (node:21) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'map' of undefined

The reason for the issue is that the peers fail to join the channel because they are not ready to be used by the callback function in joinChannel() in ./web/www/blockchain/utils.js. In order to fix this, we need to separate the functions in the line docker-compose up -d, so that the containers are built and waited long enough for all the peers to be ready.

So all you need to do is to change build_ubuntu to the code below (similarly for build_mac):

#!/bin/bash
cp ./binary_ubuntu/* .
export FABRIC_CFG_PATH=$PWD
sh ./ibm_fabric.sh
sh ./docker-images.sh
sleep 5
docker-compose up --no-start
sleep 60
docker-compose up -d

Network not found Issue

Symptoms: [client-utils.js]: sendPeersProposal - Promise is rejected: Error: 2 UNKNOWN: error starting container: API error (404): {"message":"network build-blockchain-insurance-app_default not found"}

The reason for the issue is that the network name cannot be found. To solve this, run docker network ls to figure out what the actual network name is, such as “buildblockchaininsuranceapp_default”. Go to ./peer-base.yaml and change CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE to the corresponding network name. Clean the docker containers with ./clean.sh and then rebuild the app again.

@SirCipher how did you resolve this?
