Synchronize environments error

Experience Manager (PaaS/OnPrem)
1

Hi Bloomreach developers,

At a client I am experiencing a problem with synchronizing an environment with another environment.

I followed all steps in this guide.
Both environments run on Hippo version 11.2.10-1

I performed the following steps:

  • After step 7 when I open the cms console and select a node, the right column is updated and I can see information about the selected node.

  • I logout from console.

  • When step 8 is completed I login to the cms console, the right column no longer presents node information. Not even when I navigate to other nodes (see screenshot below).

Screenshot of the target environment. Notice that right column shows no node information

I see the following stacktrace in catalina.log:

Did anyone experience this problem before and know how to resolve it?
All tips and advice are welcome :+1:

Big thanks in advance,

That’s a UI error. Try refreshing.

How are you restoring the nodes in step 8? You mention that you logout in between step 7 and 8. You also mention you restore the nodes and then log in to the console, which should be the other way around. Do you have multiple tabs open?

Hi Jasper.floor,

That’s a UI error. Try refreshing.
I tried refreshing a few times. Tried in Incognito mode and on my colleagues browsers but same result.

How are you restoring the nodes in step 8?
I manually exported the nodes from console in step 2 and imported them using the console interface context menu in step 8.

You mention that you logout in between step 7 and 8. You also mention you restore the nodes and then log in to the console, which should be the other way around.
My mistake, I didnt write it very clear. Before I start the importing in step 8, I am logged in and I can see the node information in the right-column. The console interface seems to break down after I imported the nodes.

Do you have multiple tabs open?
Just one tab.

The stack trace is a wicket error. If this is happening consistently, then something is very broken. But unless the interface is broken on some level I suspect this is a symptom. I suggest starting the process over. When restoring the nodes in step 8, delete the nodes you are replacing. Eg, restoring hippo:users, first delete the existing hippo:users.

Ok.
Does it make a difference if I save changes in the proces? Like this:

Delete node and tick the checkbox ‘save immediately’?
Import new node
Write changes to repository

or

Delete node
Import new node
Write changes to repository

That shouldn’t make any difference.
