Can’t edit existing karaoke songs - “ADD” button gives error

[tachitsuteto]

When I select an existing karaoke song that was added as ..., the form loads correctly and shows a disabled UPDATE button - which means I’m editing an existing entry.

But as soon as I change the song name, the button turns into ADD.

When I click it, nothing happens, and in the browser console I see a 500 Internal Server Error.

{"message":"insert into \"musicdex\".\"song\" (\"amUrl\", \"approver_id\", \"art\", \"available_at\", \"channel_id\", \"creator_id\", \"end\", \"id\", \"is_mv\", \"itunesid\", \"name\", \"original_artist\", \"start\", \"updated_at\", \"video_id\") values (DEFAULT, $1, DEFAULT, $2, $3, $4, $5, $6, DEFAULT, DEFAULT, $7, $8, $9, CURRENT_TIMESTAMP, $10) - duplicate key value violates unique constraint \"song_pkey\""}

So instead of updating, it tries to insert a duplicate song.

Steps:

1. Select a song titled ... from the karaoke list
2. The form shows up with a disabled UPDATE button
3. Enter the correct song name
4. The button changes to ADD
5. Click it - nothing happens

Expected:
It should stay as UPDATE, and allow updating the song.
