uSync exclude by docType

I have a need to exclude a content type (docType) from uSync. I can get it to exclude a whole node and it’s children but not the children on their own.

I have a structure of
/Courses/SubjectPage(s)/CoursePage(s)
I can exclude the whole Courses/ node, but what I want is the SubjectPages and not the CoursePages as they’re downloaded from an external source.

So using Exclude/Include Content | Jumoo docs I can exclude the courses node. Reading this old post: Can't exclude content by type · Issue #203 · Jumoo/uSync.Complete.Issues · GitHub I tried to exclude the CoursePages using this:-

 "uSync": {
    "Publisher": {
      "Handlers": {
        "Handlers": {
          "PublishedContentHandler": {
            "Settings": {
              "RulesOnExport": true,
              "ExcludeContentTypes": "coursePage"
            }
          }
        }
      }
    }
  },

It didn’t work and I’m not sure why. Could anyone help?

Thanks.

Do you want to exclude it in normal “uSync” or when you publish via uSync complete?.

The snippet is for publisher , for the normal uSync it’s in a slightly different place
