Can't do POST request on Process


#1

Hello,

I need to send POST to my process.
I using Postman application for that.
If I sent POST on http://localhost:8080/rest/process-definition/key/RegisterUser/start
I get error back.

“timestamp”: 1552241460054,
“status”: 500,
“error”: “Internal Server Error”,
“message”: “No message available”,
“path”: “/rest/process-definition/key/RegisterUser/start”

If I want send POST request on process, need I any dependences?


#2

What version of camunda are you using?
Are you using wildfly or springboot?
Have you already deployed your process?


#3

I have 2.0.0 version. Springbot.

I create process in Camunda, started project with debuger on localhost and get this error.


#4

Can you upload your model?


#5

I think it is not a model problem because I have same error on all models. Below log from debuger:
