I/O Exception after importing layout with playlists from version 2.3.17 to 4.x.x

[ifarzana]

When importing a layout with playlists containing a number of playlists from version 2.7 into version 4.x, the lkplaylistplaylist table does not correctly populate the necessary records, particularly for depth=1. As a result, the player reports that the layout is invalid and does not display it, generating the following error:

Prepare Image - I/O Exception, please check your selected storage.

Steps to Reproduce:

• Export a layout with playlists from version 2.3.17
• Import the layout into version 4.1.1.
• Schedule the layout on the player.
• Run the following query to check for missing records:

SELECT * FROM lkplaylistplaylist;
Observe that the table lacks the expected entries for depth=1.

Investigation:

• The videos in question are present and can be downloaded from the CMS library.
• The XLF in the layout editor shows the correct files.
• Upon reviewing the closure table for the playlist, it seems incomplete.

Expected Behaviour: The lkplaylistplaylist table should be fully populated with the correct records, ensuring all playlists are properly associated with the layout and the layout plays without errors

Actual Behaviour: The table does not contain the expected records for depth=1, leading to incomplete playlist associations and potential layout failures.

Workaround: Manually removing and re-adding the playlists to the layout resolves the issue, as it regenerates the missing records.

The internal layout ID 2479 in development highlights the current issue.
