Error message

Invalid category

What it means

The cybersecurityventures news route accepts a category path parameter that must be one of the predefined keys in the categories object (today, intrusion-daily-cyber-threat-alert, ransomware-minute, cryptocrime, hack-blotter, cybersecurity-venture-capital-vc-deals, mergers-and-acquisitions-report). If the provided category string does not match any key, an InvalidParameterError is thrown with a clear 'Invalid category' message.

Solutions

1. Check the route's parameters.options in the route definition to see the list of valid category values.
2. Use one of the valid categories: today, intrusion-daily-cyber-threat-alert, ransomware-minute, cryptocrime, hack-blotter, cybersecurity-venture-capital-vc-deals, mergers-and-acquisitions-report.
3. If you need a new category, add it to the categories object with the correct scene and view numbers from the Knack API.

const category = ctx.req.param('category') ?? 'today';
const validCategories = ['today', 'intrusion-daily-cyber-threat-alert', 'ransomware-minute', 'cryptocrime', 'hack-blotter', 'cybersecurity-venture-capital-vc-deals', 'mergers-and-acquisitions-report'];
if (!validCategories.includes(category)) {
    throw new InvalidParameterError(`Invalid category '${category}'. Valid options: ${validCategories.join(', ')}`);
}

function isValidCategory(cat: string): cat is keyof typeof categories {
    return cat in categories;
}

When it happens

Trigger: A user requests /cybersecurityventures/news/<category> where <category> is not a key in the categories dictionary. Object.hasOwn(categories, category) returns false. This is a pure input validation check before any API call is made.

Common situations: Typo in the category name (e.g., 'ransomware' instead of 'ransomware-minute'); user guesses a category name that doesn't exist; outdated documentation references a category that was removed; case sensitivity issue (e.g., 'Today' vs 'today').
