Hello,
For Named Account List, filtering by either name or marketoGUID returns "Invalid filter type". For example, the following rest call url gives the response in the pictures below.
https://442-cfp-713.mktorest.com/rest/v1/namedAccountLists.json?filterType=name&filterValues=Saas%20...

Any thoughts would be appreciated.
Thanks.
