We have a problem in 8.3.1 that the Litium UI never updates after operations complete in Litium Cloud behind Fastly. In development it works like it should.
When running Litium behind Fastly the timeouts need to be adjusted either in platform or in the configuration for Fastly to avoid missing update events to the UI.
We are running Litium behind Fastly.
The problem affects large parts of the UI. For example,
When adding categories in PIM, page needs to be reloaded for tree on the left to update
When adding pages in CMS, page needs to be reloaded for tree on the left to update
Product import operations just hang with the “importing” modal/lightbox/alert and no updates, but page reload shows that import has taken place
If it’s 60412, the mitigation says
Litium:ServerSentEvents.KeepaliveInterval can be used as the configuration key to configure the keepalive interval in Litium.
Not sure what to set this to to mitigate the problem.
In 8.4 the default timeout is now set to 9 sec so try to set it to 9 sec since default is 30 sec in your version or upgrade your solution would also be a good choice.
Don’t really understand why it works though. The problem doesn’t appear after 9 or 30 seconds, the problem appears instantly, in that the UI doesn’t update at all for “asynchronous” operations. Adding a PIM category takes less than a second for the left-hand category tree in the UI to update, for example, but without setting the keep-alive interval it never updates. And the product import progress bar doesn’t update at all without the interval setting.
