What causes "Category "${category}" not found" in DIYgod/RSSHub?

DIYgod/RSSHub · warning · Error

Category "${category}" not found

Error message

Category "${category}" not found

What it means

The The Wire Hindi category route keeps a static categories array and finds the requested category by exact value match. If categories.find returns undefined (the :category param matches no entry), it throws a generic Error. This is purely a client-side validation against a hardcoded list before any API call.

Solutions

Use a category value present in the route's categories array (open the route file to see valid values).
If the site has a new category, add it to the categories array with its WordPress id and label.
Throw InvalidParameterError instead of a generic Error for consistency with other routes.

Example fix

// before
const categoryData = categories.find((cat) => cat.value === category);
if (!categoryData) {
    throw new Error(`Category "${category}" not found`);
}

// after: case-insensitive match and a clearer error
const categoryData = categories.find((cat) => cat.value.toLowerCase() === category.toLowerCase());
if (!categoryData) {
    throw new InvalidParameterError(`Category "${category}" not found. Supported: ${categories.map((c) => c.value).join(', ')}`);
}

Defensive patterns

Strategy: validation

Validate before calling

const SUPPORTED = new Set(categories.map((c) => c.value.toLowerCase()));
function isSupportedCategory(c: string): boolean {
    return SUPPORTED.has(c.toLowerCase());
}
// reject unsupported categories at the route boundary

Type guard

function isTheWireHindiCategory(c: string): boolean {
    return categories.some((cat) => cat.value.toLowerCase() === c.toLowerCase());
}

Try / catch

try {
    return await handler(ctx);
} catch (e) {
    if (e instanceof Error && /Category .* not found/.test(e.message)) {
        return notFound(`Supported: ${categories.map((c) => c.value).join(', ')}`);
    }
    throw e;
}

Prevention

Use a category value present in the route's categories array.
Add new site categories to the array as they appear.
Match case-insensitively to absorb URL-casing differences.

When it happens

Trigger: Requesting /thewirehindi/<category> with a value that does not equal any cat.value in the local categories array (typo, removed category, or a category that exists on the site but was not added to the list).

Common situations: User mistypes the category; a new site category was never added to the route's array; case mismatch between the URL and the stored value.
