I am installing the DXA model extension using SDL Add-On feature by following the steps mentioned in SDL Documentation. It's stuck with Status as pending activation. I believe this might be because of something missing(maybe some rights or access to some port). I can't see any error logged into the Event viewer or Add-on service log.

I have already checked a similar TREX question DXA Model Extension got stuck in a Pending activation Status and verified that I have environment variable configured and I can access content delivery services on my content manager machine.

Can anyone suggest what else I can check?

  • Did you restart the content service after the DXA model extension install in the add-on? – Velmurugan May 25 at 14:14
  • Can you check, Is there any error anything in the content service logs? – Velmurugan May 25 at 14:20
  • Yes, I restarted the service and no error in my session content service. Wondering if this addon need any configuration? Even I can't see any changes in my Content service.. – Mukesh Kumar May 25 at 14:38
  • Can you also check "\session\extensions\dxa-model-extension.zip" this file downloaded in the extensions folder or not? also ensure content service server has access to add-on service endpoint? – Velmurugan May 25 at 14:47
  • Thanks @Velmurugan, \session\extensions folder is not available. I can access Add on service from CD server. – Mukesh Kumar May 25 at 14:52

Try the following steps to troubleshoot.

  • Ensure ContentServiceCapability registered with the discovery (DXA model extension works without configuration it's mandatory to register the ContentServiceCapability before content service restart, either install the service with auto-register or run the discovery registration and then restart the service, otherwise add-on service doesn't know about the service role)
  • Stop the add-on service and restart the session content service to leave it 2 to 3mins, I would expect session content service would go down and also expect to see this below error message in your cd_core.logs

2020-05-25 17:00:10,554 ERROR [main] AddonClientFacade - Add-on service specified by URL: 'http://localhost:83/addon' is not up and running but it's mandatory for service to work properly java.lang.RuntimeException: Retry limit exceeded. at com.sdl.delivery.addon.client.api.AddonClientFacade.registerAddonsToDownload(AddonClientFacade.java:160) at com.sdl.delivery.service.WinServiceContainer.main(WinServiceContainer.java:41) Caused by: org.springframework.web.client.ResourceAccessException: I/O error on GET request for "http://localhost:83/addon/api/v1/health": Connection refused: connect; nested

  • Also, try to enable DEBUG logs to see what it's going on
  • Ensure add-on service URL either passed in the service start-up parameters or the following below environment variables created as per your environment
    # Create the system environment variables   
    [System.Environment]::SetEnvironmentVariable('addonserviceurl','http://localhost:83/addon',[System.EnvironmentVariableTarget]::Machine)

    [System.Environment]::SetEnvironmentVariable('cdenvironment','staging',[System.EnvironmentVariableTarget]::Machine)
  • In the application.properties ensure the following properties configured
# add-on heartbeat interval. determines how often we should report live status of a service to add-on service.
# default value is every 60000 millis = 1 minute.
addon.heartbeat.interval=60000

I hope it helps

  • Thanks @Velmurugan. During debugging I saw that issue was indeed because of missing environment variables. I didn't added the cdenvironment variable to "staging" as my CD environment was having both Staging and Live services. – Mukesh Kumar May 25 at 15:57
