Hello @hassang ,

One more point to add, while i am adding details for input, it doesn’t show me all options showcase here , Is it not available for self managed version ? OR I am missing something here ?

PFB screenshot from DMN I have created,

Thanks,
Nirav.

Hi @nirav,

You only specified values for input labels whereas you should specify values for input expressions.

The missing options are related to Camunda 7 platform. (For example: the “Expression Language” option doesn’t show up when platform 8 is selected because only FEEL language is supported in platform 8)

nirav · July 18, 2022, 8:18am

Thanks @hassang , able to deploy DMN now.

Subramanya_Mulgund · July 27, 2022, 5:45am

Hello ,

this is regarding the missing options related to Camunda 7 platform (Expression Language & Input Variable) in newer version of Camunda will be incorporated in coming days to support different languages other than FEEL. May be like PYTHON,JQUERY?

Thanks in Advance

Ingo_Richtsmeier · July 27, 2022, 9:25am

Hi @Subramanya_Mulgund,

as the languages you mentined are not free of side effects, it’s unlikely that a service provider would like to have them on their cluster.

FEEL is a functional language without side effects. Python would open the door for remote code execution with DMN evaluation.

Hope this helps, Ingo

@hassang I am getting the same error, I can´t work out what the trouble is, would you help me out please? I defined all input values, types of input are correctly set up as well in terms of both intragers and strings. I am using Camunda 8.3.
