Improve error messages for DMN deployments

[sarvartojikulov]

Describe the bug

When i am deploying a DMN Diagram without filling "History cleanup", i am getting deployment error : "ENGINE-22004 Unable to transform DMN resource 'your_diagram.dmn'. [ deploy-error ]"

As i can see all mandatory fields like General > Name and General -> ID are pre-filled with default values.

Camunda Moedeler v5.19 Camunda 7.20

Steps to reproduce

1. Create DMN Diagram for Camunda v7
2. Deploy it
3. You will recieve error : "ENGINE-22004 Unable to transform DMN resource 'your_diagram.dmn'. [ deploy-error ]"

Expected behavior

• History cleanup already filled
• Properly described error message
• Description in Documentation

Environment

• OS: MacOS -> Docker
• Camunda Modeler Version: 5.19
• Execution Platform: Camunda 7.20

@jppazmin Hi, yes you should fill the Field in Decision (DMN Diagram) -> History Cleanup, Time to Live

Related to https://github.com/camunda/camunda-modeler/issues/4062.

We shall offer a proper UX that tells you about history time to live being required.

@sarvartojikulov Could you share a screenshot with the exact deployment error message you're seeing?

Thanks @sarvartojikulov. To be investigated if this is a modeler issue (not forwarding deploy errors) or a limitation of the engine (Camunda 7.20) not passing these errors.

Via https://github.com/camunda/camunda-modeler/issues/4062 and friends we'll have additional HTTL hints available for you in the properties panel (via a tooltip).

Hey guys! Just to contribute, I managed to get past the problem by setting a value for History Cleanup (Time to live) in the decision object within the ".dmn" file.
