Invalid enum form property issue

I have problem with exception: org.camunda.bpm.engine.ProcessEngineException: Invalid value for enum form property. When I select any of given option values except “NoPromise” it works, but when I select the last option it gives me an error. I don’t have any logic for this particular value.

Here is the screenshot:

does it work If you move the NoPromise line to another position in the enum?

Did you copy and paste the values? Modeler has had issues in the past with copy and paste where extra characters/content is carried over. If you inspect the XML, is there any extra content in the enum values?

Unfortunately, it was my mistake. From my angular app I’m trying to submit empty value (not null). So that is invalid value for this field. With modeller is everything ok.

Sorry for that and thanks! :grinning:
