I have this error when I try to deploy the DMN:

Here’s the DMN file attached:

Rules_F.dmn (8.9 KB)

Camunda Modeler system information

Version: 5.5.1
Operating System: Windows 10 amd64
Plugins:
Execution Platform: DMN - Camunda Platform 7

Niall · January 2, 2024, 12:18pm

Which version of Camunda 7 are you deploying this file to and how exactly are you doing the deployment?

y-io · January 2, 2024, 12:19pm

Camunda 7.18
I’m deploying using Camunda Modeler directly through a Port-Forward to a Kubernetes cluster

Niall · January 2, 2024, 12:20pm

Are you able to do a test deploy locally?

y-io · January 2, 2024, 12:31pm

If you mean, if I tested locally, yes and I can deploy the DMN without an issue:

Niall · January 2, 2024, 12:38pm

So the error is only happening when you try to deploy it to your production cluster?

y-io · January 2, 2024, 12:43pm

yes, the remote cluster (for now it’s the TEST env), next step will be production indeed

Niall · January 2, 2024, 12:52pm

So, something is going wrong with your deployment.

Did i work in the past?
What has changed since it last worked?
Can you give specific details of exactly how you’re doing the deployment (API etc.)

y-io · January 2, 2024, 3:13pm

So, I took an old file from 8 months ago, and tried to deployed it, and I get:

Well, actually, we don’t change Camunda files that often, maybe like once or twice a year… so now, I’m a bit shocked to see I can’t deploy

I have created a brand new DMN file and tried to deploy it using Camunda Modeler, I get this error:

I found this in the Camunda source code but I don’t understand why it talks about TTL in the DMN, i have a simple DMN that gets one string as an input and outputs one string…
The other error that shows in the Camunda Modeler is here

dummy.dmn (1.3 KB)

The issue is that this field is not set, so when I set it, it works -_-"

I think this is a bug; either Camunda Modeler should prevent the user from deploying if it’s not filled or init its value to 0 for example…

Thank you,

Hello @y-io,

The current behavior is intended as described here.

We are already discussing possible solutions to improve the use experience here.

Regards Tobias
