What’s Wrong Here? Hint: It's What You Don't See

no j-box for connection, and no connector on the wire

there is no box to support fixture

Well, I know that they want to make sure there are no gaps around the perimiter of the ceiling box outer shell, but that's a little overkill, not even seeing the box - oris there even a box underneath it?
or maybe one of those overzealous drywallers got a little over excited about that popcorn spary finish :)

the code requires a device box to carry the weight of the fixture.According to Art.300.15 a box is required at each splice point,outlet ,switch or termination point.

314.27 (A) (2) At every outlet used exclusively for lighting , the box shall be designed or installed so that a luminaire or lampholder may be attached.
