Invalid name

Error message

Invalid name

What it means

Thrown by the Lofter user handler (lib/routes/lofter/user.ts:31) as an `InvalidParameterError` when the `:name` path parameter fails `isValidHost()`. The name is interpolated into a subdomain (`${name}.lofter.com`), so it must be a valid DNS label.

Solutions

1. Pass only the bare subdomain label, e.g. `/lofter/user/i` (the documented default).
2. Strip protocol/host/path from the value before calling the route.
3. Verify `<name>.lofter.com` resolves in a browser.

Example fix

// before: GET /lofter/user/myblog.lofter.com
// after:  GET /lofter/user/myblog

import { isValidHost } from '@/utils/valid-host';
function resolveLofterUserName(name: string | undefined): string {
    const n = (name ?? 'i').trim();
    if (!isValidHost(n)) throw new TypeError(`Invalid Lofter user name: '${name}'`);
    return n;
}

function isLofterUserName(value: string): boolean {
    return /^[a-z0-9-]+$/i.test(value) && !value.includes('.');
}

import { InvalidParameterError } from '@/errors/types/invalid-parameter';
try {
    await fetchLofterUser(name);
} catch (e) {
    if (e instanceof InvalidParameterError && /Invalid name/.test(e.message)) {
        return { error: `Pass a bare subdomain label, not '${name}'` };
    }
    throw e;
}

When it happens

Trigger: Requesting `/lofter/user/<name>/...` where `<name>` contains dots, slashes, spaces, or other invalid hostname characters; passing a full URL or blog path instead of the bare subdomain label.

Common situations: Passing `name.lofter.com` instead of `name`; trailing slash; uppercase; underscores.
