xianyu publish price cannot be empty

Error message

xianyu publish price cannot be empty

What it means

normalizePublishArgs throws ArgumentError when the price field is null/undefined after parsePositivePrice is called. parsePositivePrice throws on bad formats, so this guard fires for missing/empty price inputs that reach it as null. The library requires a price to build the publish form.

Solutions

1. Always pass a price: publish({ price: '19.90', ... })
2. Add a required-field check on args before invoking and print a usage hint
3. Fix upstream code that drops the price key (wrong destructure or renamed field)

Example fix

// before
await publish({ title: 'Book', description: 'good' }); // price missing
// after
await publish({ title: 'Book', description: 'good', price: '19.90' });

if (kwargs.price == null || kwargs.price === '') {
  throw new Error('xianyu publish requires a non-empty price');
}

function hasPrice(args) {
  return args != null && args.price != null && String(args.price).trim() !== '';
}

try {
  await publish(kwargs);
} catch (e) {
  if (e instanceof ArgumentError && /price cannot be empty/.test(e.message)) {
    console.error('Missing price; usage: publish --title T --description D --price 19.90');
  } else throw e;
}

When it happens

Trigger: Calling normalizePublishArgs (via the data handler) with kwargs.price === null or undefined — e.g. publishing without the price argument or with the price key omitted from kwargs.

Common situations: CLI invocations missing the price flag, JSON configs where the price key was renamed or dropped, or upstream optional-chaining yielding undefined that is passed straight through.

Understand the failure class

Background: "Missing required field" and "field is required" errors: why libraries reject payloads that omit mandatory fields — this error's family across 20 libraries.
