Failed to marshall domain instance Reference

[nazarchaparov]

Hello, I have 3 domain classes:

class Song extends AuditSection implements Serializable {

    static searchable = {
        artist reference: true
        songArtists component: true
    }

    Artist artist

    static hasMany = [songArtists: SongArtist]

}

class SongArtist implements Serializable {

    static searchable = {
        only = ["artist", "sortOrder"]
        root false
        artist reference: true
    }

    Artist artist
    Song song
    Integer sortOrder

}

class Artist extends AuditSection implements Serializable {

    static searchable = {
        except = ["songArtists", "songs"]
    }

    static hasMany = [songArtists: SongArtist, songs: Song]

}

When I index the main song class I get an error (i think, plugin incorrectly finds the ref class) : `2022-07-31 13:40:33.789 ERROR --- [nio-8282-exec-4] g.p.e.index.IndexRequestQueue : Error Indexing class com.tm.aydym.Song (index: com.tm.aydym.song_write , type: song) of id 9529
