Not able to create task from xl-deploy cli - xl-deploy

Question

I want to trying to deploy the dar file using cli. I had set up the cli on one of our build machine.
I have gone through the document as well(https://docs.xebialabs.com/xl-deploy/4.5.x/climanual.html). But when I am running the below code. I am getting an error on the step where task is getting created.
# Import package
deployit> package = deployit.importPackage('demo-application/1.0')
# Load environment
deployit> environment = repository.read('Environments/DiscoveredEnv')
# Start deployment
deployit> deploymentRef = deployment.prepareInitial(package.id, environment.id)
deployit> deploymentRef = deployment.generateAllDeployeds(deploymentRef)
deployit> taskID = deployment.deploy(deploymentRef).id
deployit> deployit.startTaskAndWait(taskID)
Error:
javax.ws.rs.ProcessingException: com.thoughtworks.xstream.converters.ConversionException:

How can I fix this issue?

Here is an Example in which you can start deployment task, check each step status and print logs for Failed ones,
# Load package
package = repository.read('Applications/TestApps/1.0')
# Load environment
environment = repository.read('Environments/TestingEnv')
# Start deployment
deploymentRef = deployment.prepareInitial(package.id, environment.id)
depl = deployment.prepareAutoDeployeds(deploymentRef)
task = deployment.createDeployTask(depl)
deployit.startTaskAndWait(task.id)
# Check on deployment errors
steplist = tasks.steps(task.id)
for s in steplist.steps:
print(' Step: ' + s.description)
print(' Status: ' + str(s.state))
if str(s.state) == 'FAILED':
print('ERROR ' + s.log)
Also you can have a look on XLDeploy log file located at XLDeploy server under "XLD_INSTALL_HOME/log/deployit.log" to get more details in case of errors.
