Error: Invalid deploy result code: HTTP/1.1 500


After creating a model, when trying to publish an application in flowable-modeler, we have the following error:
Invalid deploy result code: HTTP/1.1 500

Please, we need your help urgently.


  • Make sure you also deploy flowable task app because modeler user task app API for deployment.

  • Make sure your process is error free, like no obvious syntax error.

if both doesn’t help, please share error stack trace from log.


Dear Herve,

I faced this problem many times usually when trying to use the “candidate group” feature. It sometimes work and sometimes throw this error. In case you’ve set your process up with a candidate group, try to remove it and see if it helps with the publication of the app.

I am new to Flowable and I was just going through this [](

Instant Gratification with Flowable 6

), did exactly what was shown but, still I got this error when publishing the app and I didn’t find any reference of deploying flowable task app…please let me know what I am missing.


Are you using the 6.4.1 download or building from the current code?



I am using 6.4.1 download.

2019-06-17 14:49:17.203 ERROR 13352 — [nio-8080-exec-6] o.f.u.m.s.AppDefinitionPublishService : Invalid deploy result code: HTTP/1.1 500 http://localhost:8080/flowable-task/app-api/app-repository/deployments?deploymentKey=gigapp&deploymentName=Gig+App for url

is what I got after selecting publish.

On going to localhost:8080/flowable-task, It shows the task app running and on going there, it shows the task which I have created.

Looks like there was some logic error in process, due to which I kept getting this error, it is solved now.


Are you sure you have the Flowable Task application running on localhost port 8080 in the flowable-task context root?

Best regards,



Nope, I am not sure if I have Flowable Task application running on the localhost port 8080.
I was following along with the, from there I just created a task, created a process, while publishing the process, I got this error, you can see in the link, if something is missing that I need to add, I looked over it again, but I can see I have followed all the steps till “Creating the process app”.

Error starts with something like this:

On going to localhost:8080/flowable-task/, It shows the task app running and on going there, it shows the task which I have created.

What happens if you just enter the URL http://localhost:8080/flowable-task into your browser?

It should show the Flowable Task app. Just trying to confirm the Task app is running first. You should be able to create a task manually, but there won’t be any processes to start.


My guess is that you have an extra sequence flow (arrow) in your model. Or you’ve inadvertently unlinked a sequence flow from its destination. Try moving each of your processes, gates, and start/end events in the modeler and see if there is a sequence flow that is detached.


I am getting same issue. Please let me know if you got the solution?

validate the workflow once if it has any error or not
