Invalid response

Error message

Invalid response

What it means

Thrown by the Douyu live room route when the `/betard/<id>` API response does not contain a `room` property. The betard API returns the room metadata as JSON; if the room doesn't exist or the API format changed, the `room` field is absent. This is a plain Error thrown inside a try-catch block that also catches network errors.

Solutions

1. Verify the room ID by visiting https://www.douyu.com/<id> in a browser.
2. Find the correct ID from the streamer's Douyu page URL.
3. If the API structure changed, check for RSSHub updates.

Example fix

// before
if (!response.room) {
    throw new Error('Invalid response');
}

// after
if (!response.room) {
    throw new Error(`Invalid response from Douyu betard API for room ${id}. The room may not exist or the API format has changed.`);
}

// Pre-validate the Douyu room ID
function isValidDouyuRoomId(id: string): boolean {
    return /^\d+$/.test(id) || /^[a-zA-Z0-9]+$/.test(id);
}

// Pre-flight check: verify the room exists
async function checkDouyuRoom(id: string): Promise<boolean> {
    try {
        const resp = await fetch(`https://www.douyu.com/betard/${id}`);
        const data = await resp.json();
        return !!data.room;
    } catch {
        return false;
    }
}

interface DouyuBetardResponse {
    room?: {
        room_name: string;
        show_status: number;
        room_pic: string;
    };
}

function isValidDouyuResponse(data: unknown): data is DouyuBetardResponse {
    return typeof data === 'object' && data !== null && typeof (data as any).room === 'object';
}

try {
    const feed = await fetch(`${rsshubUrl}/douyu/room/${id}`);
} catch (e) {
    if (e.message.includes('Invalid response')) {
        console.error(`Room ${id} may not exist or the Douyu API changed.`);
    }
    throw e;
}

When it happens

Trigger: The room ID doesn't exist (no streamer with that ID); the betard API returned an error object without a room field; the API endpoint structure changed; the room ID contains special characters that weren't properly handled.

Common situations: User enters an incorrect or expired room ID; Douyu restructured the betard API; the room was permanently closed by Douyu.
