Issue
While configuring Sharepoint integration following this documentation, we are facing the following HTTP 500 internal server error, and found that we have multiple versions of the connector installed.
[http-nio-8080-exec-3][code_jsp:163] {code="500", msg="", uri=/c/document_library/sharepoint/oauth2}
javax.servlet.ServletException: java.lang.ClassCastException: class com.liferay.sharepoint.rest.repository.internal.document.library.repository.authorization.oauth2.SharepointRepositoryRequestState cannot be cast to class com.liferay.sharepoint.rest.repo
sitory.internal.document.library.repository.authorization.oauth2.SharepointRepositoryRequestState (com.liferay.sharepoint.rest.repository.internal.document.library.repository.authorization.oauth2.SharepointRepositoryRequestState is in unnamed module of l
oader org.eclipse.osgi.internal.loader.EquinoxClassLoader; com.liferay.sharepoint.rest.repository.internal.document.library.repository.authorization.oauth2.SharepointRepositoryRequestState is in unnamed module of loader org.eclipse.osgi.interna
l.loader.EquinoxClassLoader)
Environment
Liferay Quarterly releases
Resolution
The documentation describes how to install the connector when it is not available out of the box in the used Liferay version, which is a mandatory step before starting to configure it.
If the connector is already available in the Liferay version used, this part need to be skipped.
To confirm the availability of the connector, you can check liferay/osgi/marketplace folder if it contains Liferay REST Connector for SharePoint or run lb | grep Sharepoint in Gogo Shell.
