Unable to publish app in modeler

Modeler remodeled
1

Hi Folks,

I’m experimenting with open source flowable 6.5 on my local machine running docker-compose. It is working great but when I try to publish my app in the modeler I receive the following error:

Error calling deploy endpoint: Connect to localhost:8080 [localhost/127.0.0.1] failed: Connection refused (Connection refused)

I think this might have something to do with my docker setup insofar as the localhost configuration is concerned. here is the section I think the problem is.. Does anyone have experience with this type of thing?

Hi Frank,

I would expect some property where to publish your app from modeler to runtime. That’s why default values were used.

Thank you, I was actually able to get past the original error but now I get the following:

flowable_modeler | 2025-12-08 11:00:08.975 ERROR 1 — [nio-8888-exec-8] o.f.u.m.s.AppDefinitionPublishService : Invalid deploy result code: HTTP/1.1 404 http://flowable-rest:8080/flowable-rest/repository/app-repository/deployments?deploymentKey=insolvencyApp&deploymentName=Insolvency+App for url

So i’ve upgraded from a “connection refused” to a “404” error.

ChatGPT is telling me that publishing apps through the Open Source version of flowable is actually disabled. This cant be right can it?

not for version 6.5

(if you want to you can still use

to download/publish your app.

I fixed my issue. It appears that when utilizing docker, I needed to establish the entire flowable all-in-one package. Here is the full docker-compose.yaml file for anyone else who runs into this issue:
