Solutions

1. Set MEDIUM_COOKIES env var keyed by the exact Medium username.
2. Copy the full Cookie header from a logged-in medium.com session.
3. Restart RSSHub to load the new config.
4. Match the cookie key to the :user path segment exactly (no @).

Example fix

// before
// no MEDIUM_COOKIES in env

// after
MEDIUM_COOKIES=johndoe=sid%3A1%3A...

const cookie = config.medium.cookies?.[user];
if (cookie === undefined) {
    throw new ConfigNotFoundError(`Set MEDIUM_COOKIES for ${user}`);
}

function hasMediumCookie(user: string): boolean {
    return Boolean(config.medium.cookies?.[user]);
}

When it happens

Trigger: Request to /medium/tag/:user/:tag with no cookie entry for that user in config — the lookup config.medium.cookies[user] returns undefined.

Common situations: Self-hosted RSSHub without MEDIUM_COOKIES; cookie key does not match the :user segment; using the public instance.
