Anonymous REST JS call error using SP2013

Problem: I am making an anonymous JavaScript REST call to a image library.  I get the error "Request failed.  The method GetItems of the type List with id ... is blocked by the administrator on the server.nundefined".

 

Resolution:  Change the ClientCallbackSettings on the web application as shown below.

 

 



$wa = Get-SPWebApplication http://www.demo.dev
$wa.ClientCallableSettings .AnonymousRestrictedTypes.Remove([microsoft.sharepoint.splist],"GetItems")
$wa.Update()
