Error message

Such feed is not supported.

What it means

Mirror of error 281 but on the Instagram web-API route handler. Thrown as `InvalidParameterError` when the `category` path param is not in `['user', 'tags']`. Same allow-list, different transport (web API with cookies instead of private login).

Solutions

  1. Use `/instagram/user/:user` or `/instagram/tags/:tag`.
  2. Add a new category to `availableCategories` in lib/routes/instagram/web-api/index.ts and implement its switch branch if extending the route.

Example fix

// caller fix
// GET /instagram/user/<username>
Defensive patterns

Strategy: validation

Validate before calling

const ALLOWED = new Set(['user','tags']);
if (!ALLOWED.has(category)) {
  throw new InvalidParameterError(`Category must be one of: ${[...ALLOWED].join(', ')}`);
}

Type guard

const isInstagramCategory = (c: string): c is 'user'|'tags' => c === 'user' || c === 'tags';

Prevention

When it happens

Trigger: Request to the web-API Instagram route with a category other than `user` or `tags`, e.g. `/instagram/location/...`. Fires at web-api/index.ts:45 before any network call.

Common situations: User mistakes the category name (e.g. `profile`, `account`, `reels`); outdated docs; typo in a feed URL.
