Search projects action in Workato for Wrike

Hi, In Wrike for Workato, Search projects action, how do you specify Metadata needed to limit the search? I am trying to limit the search by keyword in the Title.  I get the following error if I specify 'Title' for Key and 'EOD' for value

400 Bad Request: {"errorDescription":"Parameter 'metadata[][key]' is not allowed","error":"invalid_request"}
