The compute service failed when communicating with another service or server

AllanBowe — Mon, 25 May 2020 16:36:41 GMT

We have successfully:

* set up a client / secret / access token

* obtained a list of contexts from `/compute/contexts`

* performed a POST request to `/compute/contexts/{contextId}/sessions`

The response indicates that the request was successful, JSON is returned eg:

{
  "owner": "xxx",
  "state": "pending",
  "attributes": {
    "homeDirectory": "/opt/sas/viya/config/var/run/compsrv/default/92c0b34e-b423-4694-857e-de8d1cc724f3",
    "sessionInactiveTimeout": 900
  },
  "serverId": "92c0b34e-b423-4694-857e-de8d1cc724f3",
  "applicationName": "new3FDA16F449B42DE9",
  "creationTimeStamp": "2020-05-25T15:54:07.000Z",
  "stateElapsedTime": 0,
  "sessionConditionCode": 0,
  "links": [
    {
      "method": "GET",
      "rel": "self",

Note the state - *pending*.

Subsequent GET requests to this session return:

{"errorCode":5800,
 "message":"The compute service failed when communicating with another service or server.",
 "details":["traceId: a1001428b644db83"
    ,"path: /compute/sessions/92c0b34e-b423-4694-857e-de8d1cc724f3-ses0000"
  ],"links":[],"version":2,"httpStatusCode":500}

We tried this on the "SAS Studio compute context" and the "sharedcompute" context we created (pooled compute).

How do we get more information? What could be the cause of the session not being properly fired up?

So in the end we tried all the compute contexts and this one worked: "Import 9 service compute context"

Hi @AllanBowe,

Are you still experiencing this issue? I replicated your steps and cannot hit the error. Here are my calls and relevant results:

I attempted with a couple of other contexts and had similar results. If you're still experiencing the issue, let me know and I'll pass this off to someone in dev with more in-depth knowledge.

Thanks,
