FabCar Hyperledger Fabric ./startFabric.sh execution is not completely working - node.js

Question

Im experimenting Hyperledger Fabric FabCar basic example.
Successfully registered admin and user, using registerAdmin.js and registerUser.js. I am currently facing this error after running node query.js.
~/fabric-samples/fabcar$ node query.js
Store path:/home/****/fabric-samples/fabcar/hfc-key-store
Successfully loaded user1 from persistence
2020-02-21T07:08:00.564Z - error: [Remote.js]: Error: Failed to connect before the deadline URL:grpc://localhost:7051
Query has completed, checking results
error from query = { Error: Failed to connect before the deadline URL:grpc://localhost:7051
at checkState (/home/****/fabric-samples/fabcar/node_modules/fabric-client/node_modules/grpc/src/client.js:833:16) connectFailed: true }
That was mentioned similarly in my previous question
While checking docker ps -a , I could find the peer got exited
~/fabric-samples/fabcar$ docker ps -a

after checking the workflow I found that the ./startFabric.sh execution is not completely running, it got exited after INFO 001 Endorser and orderer connections initialized.

Answer 1

I solved the above issues, by editing the file start.sh from the path fabric-samples/basic-network with the below,
# wait for Hyperledger Fabric to start
# incase of errors when running later commands, issue export FABRIC_START_TIMEOUT=<larger number>
#FABRIC_START_TIMEOUT changed to 90 instead of 10
export FABRIC_START_TIMEOUT=90 #default=10
#echo ${FABRIC_START_TIMEOUT}
sleep ${FABRIC_START_TIMEOUT}
along with that I followed the answer,
I included
dns_search: .
to the peer containers in the docker-compose.yml file located in fabric-samples/basic-network with the below.
peer0.org1.example.com:
container_name: peer0.org1.example.com

dns_search: .

The above edits resolved my issues, and now ./startFabric.sh and node query.js were working properly.
