ERROR [2024-10-21 05:54:50] instagram_api: Object of type coroutine is not JSON serializable

aiograpi/aiograpi/mixins/media.py

Line 928 in 1c476d3

async def media_seen(self, media_ids: List[str], skipped_media_ids: List[str] = []):

This happens because gen() is not awaited:

aiograpi/aiograpi/mixins/media.py

Lines 956 to 958 in 1c476d3

	"reels": gen(media_ids),
	"live_vods": {},
	"reel_media_skipped": gen(skipped_media_ids),

To Reproduce

await client.media_seen([ "01234", "56789", ])

Expected behavior
The coroutine should be awaited.

Additional context
The fix should be fairly easy to apply
