Hello everyone, I’m currently working on implementing an API with Spring Boot and the Flowable engine.  
I’m facing issues while fetching a model’s XML based on its ID or key and .then updating it to deploy the model(publish it to the app).

I have tried to fetch the model using the RepositoryService,  
for example, Model model = (Model) processEngine.getRepositoryService().getModel(modelId); // this returns null.  
I have also tried using createModelQuery().modelId(modelId) or key, but no luck.

The issue seems to be related to the act\_re\_model repository table in the database, which is empty for me. All my model data is in the act\_de\_model table (deployed).

I have gone through similar posts where they suggest using the modelRepositoryService, which is a part of the Flowable Modeler service and not a public API.

Can someone please help me out with this? I’m stuck and would appreciate any guidance or assistance. Thank you.

In ACT\_DE\_MODEL table I see my bpmn20.xml entry displayed but repositoryService.createModelQuery (). modelKey (“xxx”).list() repositoryService.createModelQuery().notDeployed().list() repositoryService.createModelQuery().deployed().list() doesn’t return values because in the log I see that it queries ACT\_RE\_MODEL I have also tried loading model with ddbb id value directly repositoryService.getModelEditorSource (\<ddbb\_id\>) but result is…
