The AdvoLogix team has identified certain limitations that  presently do not have a work-around from within the application components in Salesforce. Some of these limitations may have a pending resolution from the iManage API that we have consumed within our integration. One of those limitations is documented here.

The Featured Items lightning component within the connector may sometimes cause a bad request or an internal error when retrieving a list of documents or folders or when adding a document/folder to the featured items configuration. 

To workaround this error, users can edit the lightning component properties in the lightning app builder and provide a specific library name in the component property options.
