Kenapa data yang muncul dari hasil relasi undefined

Saya ingin manampilkan data status tetapi ketika muncul undefined data status tersebut diambil dari relasi jadi relasinya di tabel list_asset memiliki nama id_pelepasanstatus nah id_pelepasanstatus tersebut di relasikan ke tabel pelepasanstatus_asset ke id_pelepasanstatus nah sedangkan yang ingin dimunculkan itu desc_pelepasanstatus yang terdapat di pelepasanstatus_asset
