Missing required query parameter: api-version when calling client.files.list()

Bug: Missing required query parameter: api-version when calling agentsClient.files.list()

Description

When calling agentsClient.files.list(), the SDK throws a RestError with the message "Missing required query parameter: api-version".

Environment

• Package: @azure/ai-agents
• Version: 1.1.0

Steps to Reproduce

1. Create an AgentsClient instance:

const agentsClient = new AgentsClient(baseEndpoint, credentials, {
    apiVersion: '2025-05-15-preview'
});

2. Call the client.files.list():

agentsClient.files.list

3. The request fails with:
   RestError: Missing required query parameter: api-version

Workaround

As a temporary workaround, we can manually inject the api-version parameter using a custom pipeline policy:

// Workaround: manually inject api-version parameter via pipeline policy
agentsClient.pipeline.addPolicy(
    {
        name: 'ApiVersionPolicy',
        sendRequest: async (request, next) => {
            const url = new URL(request.url);
            url.searchParams.delete('api-version');
            url.searchParams.set('api-version', apiVersion);
            request.url = url.toString();
            return next(request);
        }
    },
    { afterPhase: 'Serialize' }
);

// Now the client works correctly
const files = await agentsClient.files.list();
