Invalid API response

Error message

Invalid API response

What it means

Generic Error validating the parsed JSON from BNU's CMS API: it requires code === 0 AND a truthy data field. A 200-OK response whose envelope indicates failure (non-zero code) or lacks the data array is rejected here, before list mapping dereferences it.

Solutions

1. Log jsonData (code + message keys) to see the CMS's own error description and act on it.
2. Confirm the category path parameter maps to a valid columnid on the live CMS page.
3. If the envelope shape changed, update the code/data checks and the list-mapping field names.

Example fix

// before
if (jsonData.code !== 0 || !jsonData.data) {
    throw new Error('Invalid API response');
}
// after (surface the CMS code/message)
if (jsonData.code !== 0 || !jsonData.data) {
    throw new Error(`Invalid API response: code=${jsonData.code}, msg=${jsonData.message ?? 'n/a'}`);
}

const jsonData = JSON.parse(response.body);
if (jsonData.code !== 0 || !jsonData.data) {
    throw new Error(`Invalid API response: code=${jsonData.code}, msg=${jsonData.message ?? 'n/a'}`);
}

const isBnuSuccess = (j: any): boolean =>
    j && j.code === 0 && Array.isArray(j.data);

When it happens

Trigger: got.post succeeded and JSON.parse ran, but jsonData.code is not 0 (e.g. category id rejected, auth required) or jsonData.data is null/undefined/empty. The guard throws before `.map` is called on data.

Common situations: Passing a category id the CMS does not recognize; the CMS returning a permission error; the response shape changing so `data` is nested differently; an HTML error page that happened to be JSON-parseable.
