Unknown option: ${argument}

Error message

Unknown option: ${argument}

What it means

During argv parsing any token starting with `-` that does not match a known case (--html, --css, --html-file, --css-file, --browser, --timeout, --headed, --verbose, --help/-h, --) falls through to the default and throws. Only bare positional tokens (no leading dash) are tolerated as unknown.

Solutions

1. Run with --help to see the accepted flags.
2. Correct the flag spelling.
3. If a positional value starts with `-`, place it after `--`.

Example fix

# before
bun .../index.mjs --htm '<div/>'
# after
bun .../index.mjs --html '<div/>'

const known = new Set(['--html','--css','--html-file','--css-file','--browser','--timeout','--headed','--verbose','--help','-h','--'])
const unknown = argv.filter(a => a.startsWith('-') && !known.has(a))
if (unknown.length) throw new Error(`Unknown option: ${unknown[0]}`)

const isKnownOption = (a) => !a.startsWith('-') || known.has(a)

When it happens

Trigger: A misspelled flag like `--htm` or `--html-fiel`; an unsupported short flag like `-x`; a value that itself starts with `-` placed where a flag is expected.

Common situations: Typo in the flag name; copy-paste from a different tool's CLI; a negative-number positional accidentally parsed as a flag.
