Example-web pb - cannot start process

[fck]

HI I just build the Spring Boot Starter example-web sample (https://github.com/camunda/camunda-bpm-examples/tree/master/spring-boot-starter/example-web)

• I can get the process definition
  http://localhost:8080/rest/engine/default/process-definition
  [{“id”:“Sample:1:6e70bb39-e758-11e8-aab1-5efd57a1864a”,“key”:“Sample”,“category”:“http://camunda.org/schema/1.0/bpmn",“description”:null,“name”:“Sample”,“version”:1,“resource”:“BOOT-INF/classes/bpmn/sample.bpmn”,“deploymentId”:“6e316847-e758-11e8-aab1-5efd57a1864a”,“diagram”:null,“suspended”:false,“tenantId”:null,“versionTag”:null,"historyTimeToLive”:null}]

• but somehow I cannot start a process instance with a POST (basic auth) http://localhost:8080/rest/engine/default/process-definition/key/Sample/start

any idea about what I’m missing ?

Thx

What do you receive as response?

Thx for looking at my pb & sorry should have been more precise. I’m getting a 403
{
“timestamp”: “2018-11-15T14:58:13.427+0000”,
“status”: 403,
“error”: “Forbidden”,
“message”: “Forbidden”,
“path”: “/rest/engine/default/process-definition/key/Sample/start”
}

I’ve got the impression this is related to this https://docs.camunda.org/manual/7.9/reference/rest/overview/authentication/ but I don’t really know how to add a servlet filter in the context I’m using to run the engine:
java -jar ./target/camunda-bpm-spring-boot-starter-example-web-0.0.1-SNAPSHOT.jar
