Hi Jena,

please post the corresponding code which causes this problem
or describe how do you create the task.

Same problem here!

DeploymentWithDefinitionsDto deploymentDto = DeploymentWithDefinitionsDto.fromDeployment(deployment);
return Results.json().render(deploymentDto)

The model is deployed, I can see that from a call via the REST API:
{“deployments”:[{“id”:“1”,“name”:“Geoprocess”

As you can see, the outputs sohow breaks.
