Cannot use embedded forms on the app

Hello,

I’ve been working on an application using the webapp starter, and have been trying to get an embedded form to work. My project structure is very similar to the one found in examples/camunda-spring-boot-starter-example-webapp. I tried creating a folder src/main/webapp/forms with a file greetingForm.html , and modifying sample.bpmn so that the user task “do something” has form key app:embedded:forms/greetingForm.html, but I get a CORS error displayed when trying to view the form in the Tasklist.

We experienced a similar problem with a non-spring-boot Camunda project, and the issue went away when we used an META-INF/process.xml without any configuration, like:

<?xml version="1.0" encoding="UTF-8" ?>
<process-application
    xmlns="http://www.camunda.org/schema/1.0/ProcessApplication"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <process-archive>
    <process-engine>default</process-engine>
    <properties>
    </properties>
  </process-archive>
</process-application>

but the same approach doesn’t seem to work here. The problem seems to involve the contextPath being null in the response below, which is obtained by tasklist app when using the API endpoint /api/engine/engine/default/task/1408

{"key":"embedded:app:forms/greetingForm.html","contextPath":null}

Can embedded forms work with the spring boot webapp starter? Is this a bug, pending feature, or something I’m missing? Thanks!

I would suggest to raise a support ticket

Well, the same problem occurs for me when using Spring Boot 2.0.2, but setting server.servlet.contextPath doesn’t fix it for me. I don’t even get an error in my server log, just an invalid HTTP request to http://localhost:8080/forms/ergebnis-lesen.html?noCache=1529563649812&taskId=f5ddea46-751e-11e8-870f-aced5cb84e54&userId=demo

I am using the camunda-bpm-spring-boot-starter-webapp-ee with version 3.0.0.
