`admin.userConnections.list()` ignores `user.id` filter parameter

[a9a4k]

Description

The admin.userConnections.list() method returns all user connections regardless of the user.id filter parameter being provided. This forces developers to implement client-side filtering, which is inefficient and defeats the purpose of the API filter.

Expected Behavior

When calling:

const { items } = await arcade.admin.userConnections.list({
  user: { id: 'specific-user-id' },
  limit: 1000,
});

The API should return only connections for the specified user ID.

Actual Behavior

The API returns all user connections across all users, ignoring the user.id filter completely.
Reproduction

import { Arcade } from '@arcadeai/arcadejs';

const arcade = new Arcade({ apiKey: process.env.ARCADE_API_KEY });

// Request connections for a specific user
const { items: connections } = await arcade.admin.userConnections.list({
  user: { id: 'cabf97f8-7507-4777-b79d-5c4c82d06841' },
  limit: 1000,
});

console.log('Connections returned:', connections.length);
console.log('Unique user_ids:', [...new Set(connections.map(c => c.user_id))]);

// Expected: Only connections with user_id === 'cabf97f8-7507-4777-b79d-5c4c82d06841'
// Actual: Connections from multiple different user_ids

Current Workaround

We're implementing client-side filtering to get the desired behavior:

const { items: allConnections } = await arcade.admin.userConnections.list({
  user: { id: entityId },
  limit: 1000,
});

// Manual filtering required
const userConnections = allConnections.filter(
  (connection) => connection.user_id === entityId && connection.connection_status === 'active'
);
