Solutions

1. Confirm the source directory path exists before invoking the copy operation.
2. Correct the directory path argument or configuration value that produced the missing path.
3. When running from scripts, ensure the working directory is the repository root so relative paths resolve.

Example fix

Create the directory shown in the error message or fix the path argument, then rerun the publish command.

When it happens

Trigger: Thrown when copying a directory tree during publish packaging: the source directory to copy from is missing.

Common situations: Happens when a publish script references an output or assets directory that was renamed, deleted, or never built. Confirm the build produced the expected folder and that the configured source path is correct.
