dgs-framework: bug: upgrading to 4.6.0/4.7.3 leads to DgsInvalidInputArgumentException

We have this query

    spaces(
       first: Int!, 
		offset: Int!
        search: String,
        type: SpaceTypeFilter = BASIC,
        sortBy: [SpaceSortBy] = [{direction: ASC, field: TITLE}, {direction: ASC, field: ID}]
    ): SpaceGraphQlViewConnection!

input UserSortBy {
    field: UserSortByField,
    direction: SortDirection = ASC
}

enum UserSortByField {
    ID,
    USER_NAME,
    FIRST_NAME,
    LAST_NAME,
    COMPANY,
    EMAIL
}

enum SortDirection {
    ASC,
    DESC
}

While this works just find with 4.5.1, we get an exception in 4.6.0/4.7.0

Not sure I can understand what changed in this regard by the Changelogs - did we do something wrong in the first place?

Thanks
