query.js crash on Hyperledger fabric fabcar example - hyperledger

Question

The fabcar example of the hyperledger tutorial crashes for me at the step of attempting to run query.js.
I have removed all hyperledger related docker images (with docker rmi), so all required content was downloaded automatically when running startFabric.sh. The output on startup looks slightly "clouded" but not very suspicious (I skipped the lengthy output about the images being downloaded):
# wait for Hyperledger Fabric to start
# incase of errors when running later commands, issue export FABRIC_START_TIMEOUT=<larger number>
export FABRIC_START_TIMEOUT=10
#echo ${FABRIC_START_TIMEOUT}
sleep ${FABRIC_START_TIMEOUT}
# Create the channel
docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin#org1.example.com/msp" peer0.org1.example.com peer channel create -o orderer.example.com:7050 -c mychannel -f /etc/hyperledger/configtx/channel.tx
flag provided but not defined: -e
See 'docker exec --help'.
The next step as asked is
npm install
It also delivers mostly ok output,just one warning:
npm WARN fabcar#1.0.0 No repository field.
I have verified images are running (also shows that the user is authorized to use the docker, while the user is otherwise not root):
docker ps

When I finally try to run
node query.js
I observe the following errors:
Create a client and set the wallet location
Set wallet path, and associate user PeerAdmin with application
Check user is enrolled, and set a query URL in the network
Make query

I have checked this but my node.js version is correct:
node --version
v6.11.2
npm -- version
{ fabcar: '1.0.0',
npm: '3.10.10',
ares: '1.10.1-DEV',
http_parser: '2.7.0',
icu: '56.1',
modules: '48',
node: '6.11.2',
openssl: '1.0.2l',
uv: '1.11.0',
v8: '5.1.281.103',
zlib: '1.2.11' }
Also, the error message is completely different. The machine has ports 8080 and 8443 in use, but when I tired to shut down the applications using them, was not helpful.

That's because you didn't follow the steps.. as it says, before query.js u should enroll the admin and register user, then it works properly. And don't pay attention to "npm WARN fabcar#1.0.0 No repository field", it works well. Try the following:
$docker stop $(docker ps -a -q)
$docker ps -qa|xargs docker rm
$./startFabric.sh
$cd fabric-samples/fabcar/javascript
$node enrollAdmin.js
$npm install
$node registerUser.js
$node query.js
