Can't create an application: Error "code": 404 "description": "The server has not found anything matching the request URI"

Hi

I am trying to create my own application, following the steps from the getting started tutorial and the procurement request example.

My process is running ok in the portal, but I can´t make it run as an application

When I try to start the process (instantiation form), I get this error:

{ “code”: 404, “contactEmail”: null, “description”: “The server has not found anything matching the request URI”, “homeRef”: “/”, “reasonPhrase”: “Not Found”, “uri”: “http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.4.5” }

It seems to me that I did everything right, maybe I’m missing something. I have no idea how to proceed, can anyone help me?

Thank you
