Files remain “Unmoved”

#1

Rename Files fails to move fully matched album – baseFolder is null (12.8 Docker)

I’m running SongKong 12.8 Gish Docker (Premium).

I have an album under:

/music/Processing/Unmatched/…

I used Match to One Album and manually selected the correct MusicBrainz release. Report 64 confirms:

  • Matched to MusicBrainz release
  • All 18 songs on the release are matched
  • MB Release ID is present
  • Individual MB Track IDs are present

My Rename Files task is configured with:

  • Move Folder: /music/Library
  • Move Unmatched Folder: /music/Processing/Unmatched

The Rename Files report correctly identifies the Base Folder as:

/music/Processing/Unmatched

However, running Rename Files does not move any of the 18 files. Report 67 says “No changes were made” and the Activity Log contains:

Cannot invoke “java.nio.file.Path.toString()” because “baseFolder” is null

I also tested changing “If song moved to another folder move” from Everything to music-only, with the same result.

It therefore seems that the album is correctly matched and the source/destination folders are correctly configured, but the Rename Files move operation is hitting a null Base Folder internally.

I have uploaded support files containing the relevant reports/logs.

Hi, no support files seem to have been uploaded, I cannot resolve the issue without the support files.
