Error in Moving versionables between Component

Hello,

We are trying to move files between components in a workspace using workspaceConnection.moveVersionablesBetweenComponents method

our method:

IComponentHandle compHandleFrom = getComponentHandle(srcComponentExactNameSFM);

IComponentHandle compHandleTo = getComponentHandle(trgComponentExactNameSys);

IComponent component = (IComponent) teamRepository.itemManager().fetchCompleteItem(compHandleFrom,

IItemManager.DEFAULT, monitor);

String sourceComment = "Moving files from source to target";

String targetComment = sourceComment;

String repositoryWorkspaceName = "Example Workspace";

IWorkspaceConnection workspaceConnection = findStreamORRepositoryWorkspaceByName(teamRepository,

repositoryWorkspaceName, 2, monitor);

IConfiguration compConfigForSource= workspaceConnection.configuration(compHandleFrom);

IFolderHandle parentForSourceComp = compConfigForSource.rootFolderHandle(monitor);

Map<String, IVersionableHandle> versionableMapForSource = getVersionablesforAllFiles(compConfigForSource, component,parentForSourceComp , monitor);

IVersionableHandle[] filesToMove = getFilesToMove(functionsList, monitor, versionableMapForSource);

IConfiguration compConfigForTargetComp = workspaceConnection.configuration(compHandleTo)

IFolderHandle parentForTargetComp = compConfigForTargetComp.rootFolderHandle(monitor);

IFolderHandle[] targetFolderHandle =getFolderHandleForTarget(parentForTargetComp,compConfigForTargetComp, monitor);

IUpdateReport report = workspaceConnection.moveVersionablesBetweenComponents(compHandleFrom,compHandleTo,filesToMove, targetFolderHandle, sourceComment, targetComment, monitor);

We are getting this error at workspaceConnection.moveVersionablesBetweenComponents(compHandleFrom,compHandleTo,filesToMove, targetFolderHandle, sourceComment, targetComment, monitor); 

error is
