Error message

暂不支持对${type}的订阅

What it means

InvalidParameterError thrown by the bangumi.tv subject index route's switch on the :type parameter. Implemented cases are episodes, comments, blogs, topics; any other type falls into default and is rejected with a Chinese message ('subscription for {type} is not yet supported').

Solutions

1. Use one of the implemented types: episodes, comments, blogs, topics.
2. To add support, implement the fetcher and add a case branch before default.

Example fix

// before
default:
    throw new InvalidParameterError(`暂不支持对${type}的订阅`);

// after: list supported types in the message
const SUPPORTED = ['episodes', 'comments', 'blogs', 'topics'];
if (!SUPPORTED.includes(type)) {
    throw new InvalidParameterError(`Unsupported type: ${type}. Supported: ${SUPPORTED.join(', ')}`);
}

const SUPPORTED = ['episodes', 'comments', 'blogs', 'topics'] as const;
if (!SUPPORTED.includes(type)) {
    throw new InvalidParameterError(`Unsupported type: ${type}. Supported: ${SUPPORTED.join(', ')}`);
}

const SUPPORTED_TYPES = new Set(['episodes', 'comments', 'blogs', 'topics']);
function isSupportedType(v: string): boolean {
    return SUPPORTED_TYPES.has(v);
}

When it happens

Trigger: Requesting the route with a type value outside {episodes, comments, blogs, topics}, e.g. 'reviews', 'characters', or a typo like 'comment'.

Common situations: User assumes every Bangumi subject tab has a feed; outdated example URL; new Bangumi feature requested but not implemented.
