weibo delete: id cannot be empty

Error message

weibo delete: id cannot be empty

What it means

normalizePostId validates the id argument for the weibo delete command. If the raw input trims to an empty string, there is nothing to normalize or resolve, so it throws ArgumentError immediately before any URL parsing.

Solutions

1. Pass a valid id: numeric idstr, mblogid, or a weibo.com/cn post URL, e.g. weibo delete --id 5012345678901
2. Check the shell variable holding the id is actually set (echo "$POST_ID") before invoking the CLI
3. Copy the id from `weibo me` or `weibo post` output columns (id / mblogid) rather than retyping it

Example fix

// before
weibo delete --id "$POST_ID"
// after
: "${POST_ID:?POST_ID is not set}"
weibo delete --id "$POST_ID"

function isValidDeleteArg(id) {
  return typeof id === 'string' && id.trim().length > 0;
}
if (!isValidDeleteArg(process.env.POST_ID)) throw new Error('POST_ID is empty');

function isNonEmptyString(v) {
  return typeof v === 'string' && v.trim().length > 0;
}

try {
  await cliDelete({ id: rawId });
} catch (err) {
  if (err instanceof ArgumentError && /id cannot be empty/.test(err.message)) {
    throw new Error('Provide --id: numeric idstr, mblogid, or weibo post URL');
  } else throw err;
}

When it happens

Trigger: Calling `weibo delete` with no --id value, an --id of "" or whitespace, or passing kwargs.id as null/undefined from a script that failed to capture the id from a previous command's output.

Common situations: Shell variable interpolation producing an empty string (e.g. $POST_ID unset), copy-paste losing the id, or a wrapper script forwarding a null id from upstream JSON.
