DEPLOYMENT_ID is null in ACT_RE_MODEL table (v5.16)

[cold_gin]

Hello. I would like to retrieve the process definition using deployment ID as per this api:

ProcessDefinition pd = processDefinitionQuery.deploymentId(respositoryService.getModel(myModelIdToLookup).getDeploymentId()).singleResult();

However, the deployment ID is not populated (null) in both the ACT_RE_MODEL or the ACT_RE_PROCDEF tables, and as a result, this portion of the call returns null:

respositoryService.getModel(myModelIdToLookup).getDeploymentId()

Is this a bug? If not, how can I lookup a ProcessDefintion object? I have not been able to determine another way to get this, other than with deployment ID.

Activiti version is 5.16.

Thanks.

How did you create this model? Using the API? If so, you'd need to set the deploymentId on the object itself.
