How to run corda kotlin example correctly - corda

Question

Problem:
I am trying Corda official documentation hello word application. After Deploying CorDapp I issued
start IOUFlow iouValue: 99, otherParty: "O=PartyB,L=New York,C=US"
This command on Party A. After doing that I tried to check the ledger state by issuing this command on Party A and B.
run vaultQuery contractStateType: com.template.states.IOUState
But it gives the same output as the notary like this.
states: []
statesMetadata: []
totalStatesAvailable: -1
stateTypes: "UNCONSUMED"
otherResults: []
But Output should be like this.
states:
- state:
data:
value: 99
lender: "C=GB,L=London,O=PartyA"
borrower: "C=US,L=New York,O=PartyB"
participants:
- "C=GB,L=London,O=PartyA"
- "C=US,L=New York,O=PartyB"
contract: "com.template.contract.IOUContract"
notary: "C=GB,L=London,O=Notary"
encumbrance: null

This is my build.gradle task deployNodes.
task deployNodes(type: net.corda.plugins.Cordform, dependsOn: ['jar']) {
nodeDefaults {
projectCordapp {
deploy = true
}
cordapp project(':contracts')
cordapp project(':workflows')
}
directory "./build/nodes"
node {
name "O=Notary,L=London,C=GB"
notary = [validating : true]
p2pPort 10002
rpcSettings {
address("localhost:10003")
adminAddress("localhost:10043")
}
}
node {
name "O=PartyA,L=London,C=GB"
p2pPort 10005
rpcSettings {
address("localhost:10006")
adminAddress("localhost:10046")
}
rpcUsers = [[ user: "user1", "password": "test", "permissions": ["ALL"]]]
}
node {
name "O=PartyB,L=New York,C=US"
p2pPort 10008
rpcSettings {
address("localhost:10009")
adminAddress("localhost:10049")
}
rpcUsers = [[ user: "user1", "password": "test", "permissions": ["ALL"]]]
}
}
I tried a lot to find out a solution to this problem on the internet but I was unable to do so as I am a newcomer to Corda. Can someone help me to solve this issue? Thank you very much.

If you didn't get anything on the screen, then the flow didn't complete.
Check the logs of your nodes (inside build/nodes/PartyA/logs).
You can also start the node in debug mode (https://docs.corda.net/node-commandline.html#enabling-remote-debugging) and put breakpoints on your code to see where it's failing.
