Server "not compatible" with Liferay Sync?
Regular Member Posts: 112 Join Date: 9/20/11 Recent Posts
I have Liferay 7.2 dxp installed and am now trying to get Sync set up. I deployed the sync plugin and in the app manager I see that it's installed. When I try to set up the desktop client on my Mac, I get a message "This server is not compatible with Liferay Sync" as soon as I enter the URL. In catalina.out I see this: 
2020-07-21 14:40:48.309 ERROR [http-nio-8080-exec-10][JSONWebServiceServiceAction:114] No JSON web service action with path /sync-web.syncdlobject/get-sync-context and method GET for sync-web

So as soon as I enter the URL in the client, it hits the server and the server sends back the "not compatible" response? Can someone help me here?

I've also just noticed that when starting up LR there are errors, so it seems that Sync may not have deployed correctly. Fwiw, I have to LR 7.2 installations- one on OSX and one on an Ubuntu VM. The problems are occurring with both of them.

It sounds like the Sync Connector plugin is not installed. Please install the connector from the marketplace: link.
You will also need to install the prerequisite OAuth 1.0 Connector: link.

I already installed the Sync Connector plugin, as I mentioned in the original post. I didn't know about the OAuth plugin, I've installed now that but when I restart the server I still get the same error: org.osgi.framework.BundleException:

Could not resolve module: com.liferay.sync.security [1122]_  Unresolved requirement: Import-Package: com.liferay.portal.kernel.exception; version="[8.1.0,9.0.0)"_ [Sanitized]

 When I try to connect using the desktop client it fails with this stack trace:

You may need to upgrade to fix pack 2 or above. The Marketplace page indicates the minimum requirement for DXP 7.2 is FP2.
