Question

RDM export API is getting failed and is not working properly. 

{
  "errorCode": 400,
  "errorMessage": "Task with type [exportLookups] is running",
  "innerErrorData": {
    "exception": "com.reltio.rdm.RDMException:Task with type [exportLookups] is running",
    "stack": [
      "com.reltio.rdm.service.TaskService.create at TaskService.java, line 35",
      "com.reltio.rdm.rest.controller.ExportController.createTask at ExportController.java, line 96",
      "com.reltio.rdm.rest.controller.ExportController$$FastClassBySpringCGLIB$$a687be1b.invoke at <generated>, line -1",
      "org.springframework.cglib.proxy.MethodProxy.invoke at MethodProxy.java, line 204",

We have to try to resubmit it but an export API failed message has occurred.  Why is this happening?

Answer

The error message is self-explanatory. "Task with type [export lookups] is running". I see RDM export lookups 7c304ad5-9651-441b-aa58-1bf1de1e31cd is running.  This can be checked by processing the following API in POSTMAN.

Request:

GET https://{{rdm-service}}/tasks/{{tenantId}}
Authorization: Bearer {{token}}

Response

[
  {
    "id": "0093e14f-5335-4823-b64b-46bedd967fe9",
    "type": "reindex",
    "tenantId": "forTask",
    "createdBy": "andrey.hudyakov@reltio.com",
    "createdTime": 1503397780502,
    "status": "NOT_STARTED",
    "parameters": {
        "uris": [
            "rdm/Country/RF",
            ...
            "rdm/Country/USA"
        ]
    }
  }
]

If any tasks are processing, this is the cause.  Any task can be completed by perform the following

Request:

DELETE https://{{rdm-service}}/tasks/{{tenantId}}
Authorization: Bearer {{token}}

Response

{
    "status": "success"
}
