When attempting to install patches via API (api/1.3/patch/installpatch) , I'm receiving the following error message.  The patches are all Windows platform patches.  I'm assuming it may be that the patches are not of the same type that it is not happy about.  How can I determine the type when retrieving the patch list (api/1.3/patch/allpatches)? If type is not the issue, then any other suggestions?
