Invalid type: ${type}

Error message

Invalid type: ${type}

What it means

The Gamebase route supports a `type` path parameter validated against a `types` map containing only `newslist` and `r18list`. An `hasOwnProperty` check throws InvalidParameterError for any other value before the API call is made.

Solutions

Use `newslist` (default) or `r18list`.
Omit the type segment to fall back to `newslist`.

Example fix

// before
//   /gamebase/news/latest
// after
//   /gamebase/news/newslist

Defensive patterns

Strategy: validation

Validate before calling

const types = { newslist: 'newsList', r18list: 'newsPornList' } as const;
function isValidType(type: string): type is keyof typeof types {
  return Object.prototype.hasOwnProperty.call(types, type);
}

Type guard

function isValidType(type: string): type is keyof typeof types {
  return Object.prototype.hasOwnProperty.call(types, type);
}

Prevention

Use a `const` object + keyof narrowing so the compiler tracks valid values.
Document the two types in the route description.

When it happens

Trigger: `/gamebase/news/<type>` where <type> is not `newslist` or `r18list` — e.g. `/gamebase/news/latest`, `/gamebase/news/top`.

Common situations: Guessing a type value; typos; omitting the segment is safe (defaults to newslist).
