Error message

e.getMessage()

What it means

ByteUnitToIntegerConverter.convert wraps the underlying IllegalArgumentException from validateSizeString into picocli's TypeConversionException, forwarding the original message (hence 'e.getMessage()') when the CLI value is not a valid byte size.

Solutions

1. Fix the size argument format per the converter message (e.g., 10M, 1G)
2. Ensure the value fits in an int after unit expansion
