Common issues people run into

The YAML contains real syntax problems and formatting alone cannot fix it.

Fix: Use a YAML validator if the file may actually be invalid.

Tabs and broken indentation produce confusing output.

Fix: Replace tabs with spaces and review nesting carefully.

The user expects schema validation rather than simple formatting.

Fix: Use a validator or schema-aware tool when correctness matters more than layout.
