Process Instance started over REST are not showing

[twiinart]

I am trying to start a process instance over REST API with the below POST which seems to be working well:

POST http://localhost:8080/activiti-rest/service/runtime/process-instances
With the following json contant in the body:

{
    "processDefinitionId":"SimpleVariableProcess2:1:210004",
    "variables": [
      {
        "name":"id",
        "value":"test_id"
      },
      {
        "name":"href",
        "value":"test_href"
      },
      {
        "name":"name",         
        "value":"test_name"
      }
   ]
}

If I am posting this everything seem to be fine. I get an 201 Created and the following JSON answer:
{
  "id": "215305",
  "url": "http://localhost:8080/activiti-rest/service/runtime/process-instances/215305",
  "businessKey": null,
  "suspended": false,
  "ended": true,
  "processDefinitionId": "SimpleVariableProcess2:1:210004",
  "processDefinitionUrl": "http://localhost:8080/activiti-rest/service/repository/process-definitions/SimpleVariableProcess2:1:...",
  "activityId": "endevent1",
  "variables": [],
  "tenantId": "",
  "completed": true
}

But If I am searching with a GET in all the process instances it does not show up there e.g:
GET http://localhost:8080/activiti-rest/service/runtime/process-instances/215305

With that I get 404 Not found and the JSON answer:
{
  "message": "Not found",
  "exception": "Could not find a process instance with id '215305'."
}

What am I doing wrong?

Thank you for your help

May be it has started but not persisted to db yet. I came across this kind of thing earlier.

[twiinart]

And how would I ensure that it has been persisted in the db?

[jbarrez]

That sounds very odd … do you have an example process that we can try with those REST calls? When you get back a 201, it should be persisted.

[twiinart]

thank you for your answer. It happens with every process. For example with the process below (just a start and stop event):

Even more strange is that, if I look into the database (table ACT_HI_PROCINST) the process instance seems to be there (ID_ 17629):

<code>
ID_ PROC_INST_ID_ BUSINESS_KEY_ PROC_DEF_ID_ START_TIME_ END_TIME_ DURATION_ START_USER_ID_ START_ACT_ID_ END_ACT_ID_ SUPER_PROCESS_INSTANCE_ID_ DELETE_REASON_ TENANT_ID_ NAME_

</code>

But If I call the REST API for the this process instance with GET "http://localhost:8080/activiti-rest/service/runtime/process-instances/17629" I get back:
<code>
{
  "message": "Not found",
  "exception": "Could not find a process instance with id '17629'."
}
</code>

and if I just call the REST API for all process instances with GET "http://localhost:8080/activiti-rest/service/runtime/process-instances/" I get back:
<code>
{
  "data": [],
  "total": 0,
  "start": 0,
  "sort": "id",
  "order": "asc",
  "size": 0
}
</code>

As I have shown above there are several process instance which should be returned, but are not 😞

[jbarrez]

a start->end process immediately is finished. If you want to be able to query like you do, your process needs to have a wait state (like a user task).

OK, thank you for the clarification
