Invalid type parameter

Error message

Invalid type parameter

What it means

Thrown by the BUPT (Beijing University of Posts and Telecommunications) jwc route when the `type` parameter is neither 'tzgg' (通知公告) nor 'xwzx' (新闻资讯). Uses an if/else chain ending in a plain `Error` rather than `InvalidParameterError`, so it is reported as a generic failure.

Solutions

1. Use only `/bupt/jwc/tzgg` or `/bupt/jwc/xwzx`.
2. Maintainers: switch to `InvalidParameterError` and document the two valid values in the route description.

Example fix

// before
throw new Error('Invalid type parameter');
// after
import InvalidParameterError from '@/errors/types/invalid-parameter';
throw new InvalidParameterError("Invalid type parameter. Use 'tzgg' or 'xwzx'");

const BUPT_JWC_TYPES = ['tzgg', 'xwzx'] as const;
function validateBuptType(type: string): void {
    if (!(BUPT_JWC_TYPES as readonly string[]).includes(type)) {
        throw new Error(`Invalid type '${type}'. Use 'tzgg' or 'xwzx'.`);
    }
}

const BUPT_JWC_TYPES = ['tzgg', 'xwzx'] as const;
type BuptJwcType = typeof BUPT_JWC_TYPES[number];
function isBuptJwcType(v: string): v is BuptJwcType {
    return (BUPT_JWC_TYPES as readonly string[]).includes(v);
}

When it happens

Trigger: Requesting `/bupt/jwc/<type>` with type not equal to 'tzgg' or 'xwzx'. Examples that fail: `/bupt/jwc/jwgg`, `/bupt/jwc/bks`, `/bupt/jwc/`.

Common situations: Confusing this route's type vocabulary with the buct/gr route's, or guessing a category from the jwc.bupt.edu.cn sidebar that is not wired up here.
