Unknown option: ${argument}

Error message

Unknown option: ${argument}

What it means

Thrown by the default branch of the option-parsing switch in parsePreviewArgs when an argument starts with an unrecognized flag. Unlike index.mjs, pr-preview.mjs treats any unrecognized token as an error rather than a positional.

Thrown at packages/tailwind-play-share/pr-preview.mjs:84

Solutions

1. Run `--help` to list the accepted flags for pr-preview.mjs.
2. Remove or correct the unknown flag.
3. Use index.mjs (not pr-preview.mjs) for HTML/CSS input flags.

Example fix

// before
bun packages/tailwind-play-share/pr-preview.mjs --html '<div/>' --base-sha a --head-sha b --output o.json

// after
bun packages/tailwind-play-share/index.mjs --html '<div/>' --css ''

const KNOWN_FLAGS = new Set(["--base-sha", "--head-sha", "--output", "--browser", "--timeout", "--verbose", "--help", "-h"])
function onlyKnownFlags(argv) {
  for (const a of argv) if (a.startsWith("-") && !KNOWN_FLAGS.has(a)) throw new Error(`Unknown option: ${a}`)
}

try {
  options = parsePreviewArgs(argv)
} catch (error) {
  if (error.message.startsWith("Unknown option:")) {
  // show --help and correct the flag
  }
  throw error
}

When it happens

Trigger: Passing a flag the parser does not know (e.g. --html, --css, --headed, --sha, -v) to pr-preview.mjs.

Common situations: Confusing pr-preview.mjs options with index.mjs options, a typo in a flag name, or passing --help-style flags that do not exist for this entry point.
