Content Download Issue

When i try to download a content (the issue not happends for all content) from the App Center Admin Console i receive this message;

"error_code": "INVALID_VALUE",
"extra": {
"field": "content_version_uuid"

Our App Center installation (4.0) it's made OnPremise with NetworkLoadBalancer for HA (with two CentOS FE server and MySQL DB)

It seems that the file uploaded on the app center was cached only on one FE Server and not in all two FE servers, because if I access directly using internal IP to One FE I can download the Content, but if i access on the other FE Server i receive the Above error message.

Do you know why / how to solve that issue ?

Thanks and regards,

Hi Daniele,

In an on-premise installation, the product works as follows:

  1. Request for content or app is made from the device
  2. Front-end server checks if the item exists/is already cached locally
  3. If the item does not exist, a request is made to the DB where the item is stored, and the item is then saved/cached on that front-end server moving forward

So, the behavior you have described is not expected and should not be occurring; the content should be available/retrievable from both FE servers. I would recommend the following:

  1. Delete and re-upload the content file and test again
  2. Verify the behavior is isolated to that single content file, all other content works as expected
  3. Identify anything unique to that content file (what file type is it? is there anything special about that file?)
  4. If the issue persists, review the following log file for the time period when the error occurs: /var/log/nukona/appstore.log

I'd be interested to hear if the issue still persists, Daniele, and whether any of Andrew's tips have been helpful.  This is an issue I hadn't seen before in our load-balanced customer environments.
