weibo user-posts id cannot be empty

Error message

weibo user-posts id cannot be empty

What it means

ArgumentError thrown by readRequiredId when the `id` argument to `weibo user-posts` is empty, whitespace-only, null, or undefined. The command requires a user id (or profile identifier) to know whose posts to fetch, and refuses to run with a blank value.

Solutions

1. Pass a non-empty user id: `weibo user-posts <id>`
2. Verify the upstream variable actually contains the id before invoking (echo it or add a shell check)
3. Look up the correct id from the user's weibo.com profile URL

Example fix

// before
weibo user-posts "$WEIBO_ID"
// after
[ -n "${WEIBO_ID:-}" ] || { echo 'WEIBO_ID is empty'; exit 1; }
weibo user-posts "$WEIBO_ID"

const id = String(process.env.WEIBO_ID ?? '').trim();
if (!id) {
    throw new Error('weibo user-posts requires a non-empty id');
}
await weiboUserPosts({ id });

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

try {
    await weiboUserPosts({ id });
} catch (err) {
    if (err instanceof ArgumentError && String(err.message).includes('id cannot be empty')) {
        console.error('Provide a Weibo user id, e.g. `weibo user-posts <id>`');
    } else throw err;
}

When it happens

Trigger: Running `weibo user-posts ""` or `weibo user-posts` with no positional id, or passing a value that is only whitespace (String(raw ?? '').trim() yields '').

Common situations: Shell variable holding the id was unset (`weibo user-posts "$UID_VAR"` with empty var); scripting pipelines where an upstream extraction produced an empty string; forgetting the positional argument entirely.
