Error message

成功获取数据对象，但未找到作品基本信息

What it means

The dehydrated React Query was found and its state.data was non-null, but state.data.work is missing. This is a shape-level mismatch: the API response object exists but does not contain the expected 'work' property that holds manga metadata (title, authors, summary, cover, episodes).

Solutions

1. Log the full data object to see its actual top-level keys.
2. Tighten the queryKey matching to avoid accidentally matching a non-work query.
3. Check if the API now nests work data under a different key (e.g., data.result.work or data.data.work).
4. Verify the manga ID is valid by checking the API response status.

Example fix

// before
const data = workQuery.state.data;
const work = data.work;
if (!work) {
    throw new Error('成功获取数据对象，但未找到作品基本信息');
}

// after — expose available keys
const data = workQuery.state.data;
const work = data.work;
if (!work) {
    throw new Error(`Data object missing 'work' key. Available keys: ${Object.keys(data).join(', ')}`);
}

function hasWorkData(data: any): data is { work: { title: string; authors: any[]; summary: string } } {
    return data != null && typeof data === 'object' && typeof data.work === 'object' && data.work != null;
}

When it happens

Trigger: workQuery.state.data is truthy but data.work is undefined or null. This can happen when the API response embeds work data under a different key, when the response represents an error state (e.g., { error: '...' }), or when the query resolved with partial data.

Common situations: The API response schema changed — 'work' was renamed or nested one level deeper; the manga was deleted and the API returns a soft-error object with status but no work field; a different query (e.g., a related-works query) was matched by the loose 'work' substring check and contains unrelated data.
