Solutions

1. Verify the source directory path is correct and the directory exists before running the publish/patch command.
2. Create the missing directory or fix the path passed as sourceDir.
3. If the path is built from relative segments, run the tool from the repository root so relative paths resolve correctly.

Example fix

Check the path in the exception message, then create it (e.g. mkdir <sourceDir>) or correct the --sourceDir argument and rerun the command.

When it happens

Trigger: Thrown when generating a binary delta patch (bsdiff) during publish: the source directory passed to the patch-generation command does not exist on disk, so the tool cannot enumerate its subdirectories.

Common situations: Occurs during local publish/CI runs when the build output folder was not produced, was cleaned, or a wrong relative/absolute path was supplied to the bs-patch generation step. Verify the source path exists and the preceding build step completed.
