The description of the **success response body** for the [endpoint](https://flowable.com/open-source/docs/bpmn/ch15-REST/#get-diagram-for-a-process-instance):

```auto
GET runtime/process-instances/{processInstanceId}/diagram

```

Is not correct:

```auto
{
   "id":"7",
   "url":"http://localhost:8182/runtime/process-instances/7",
   "businessKey":"myBusinessKey",
   "suspended":false,
   "processDefinitionUrl":"http://localhost:8182/repository/process-definitions/processOne%3A1%3A4",
   "activityId":"processTask"
}

```

It actually returns a process diagram (blob):

You are right @Robinyo.

This is in [this](https://github.com/flowable/flowable-engine/blob/master/docs/docusaurus/docs/bpmn/ch15-REST.md) place in the source code. Would you like to provide a PR with the improved text?

Cheers,  
Filip
