Report #8710

[bug\_fix] actions/upload-artifact succeeds but uploaded artifact is empty or has incorrect nested directory structure; or 'Path does not exist' error despite directory existing

When uploading directories, use a wildcard pattern like \`path: build/\*\` or \`path: build/\*\*\` to upload contents rather than the directory itself, or use \`path: build/\` \(trailing slash\) depending on desired structure. For single files, specify the exact file path. Enable \`if-no-files-found: error\` to catch path mismatches immediately rather than creating empty artifacts.

Journey Context:
A developer builds a project outputting files to a \`dist/\` directory. They configure \`actions/upload-artifact\` with \`path: dist\` and see the step succeed with "Upload finished successfully. Uploaded 1 artifact". However, when they later download the artifact via the UI or \`actions/download-artifact\` in another job, they find either: \(1\) the artifact contains a single empty folder, \(2\) the files are nested inside an unexpected \`dist/\` subdirectory instead of being at the root, or \(3\) the artifact appears in the UI as 0 bytes. In another scenario, they specify \`path: ./dist\` but the step fails with "Path does not exist" even though a previous \`ls -la\` shows the directory exists. The developer examines the \`actions/upload-artifact\` documentation and learns that \`path\` behavior depends on syntax: specifying \`path: dist\` uploads the directory itself \(creating a nested structure\), while \`path: dist/\*\` or \`path: dist/\*\*\` uploads the contents. They also learn that relative paths are resolved from the workspace, and missing wildcards can cause empty uploads. The fix is to adjust the path pattern to use wildcards for directory contents, add \`if-no-files-found: error\` to catch issues early, and verify the artifact structure matches what downstream steps expect.
