The problem is that the `TallyApiClientConfig` interface has optional properties (`oauth2Config?` and `tokenStorage?`), but when we use `Required<TallyApiClientConfig>`, TypeScript expects all properties to be non-optional. However, we're still assigning potentially undefined values to them. Let me fix this by properly handling the optional properties in the configuration: --- --- I see the issue. The TypeScript configuration has `exactOptionalPropertyTypes: true` which is causing stricter type checking.

Subtask 3.2 is now marked as done. Let me also update the subtask with a final summary of what was accomplished: --- --- Excellent! Now let me check what the next task should be: --- --- Perfect! The next task to work on is **Subtask 3.3: "Add request/response interceptors for authentication and error handling"**. This is the logical next step since we've completed the OAuth 2.0 implementation and now need to enhance the interceptors for better authentication and error handling. ## Summary I have successfully completed **Subtask 3.2: "Implement OAuth 2.0 authentication flow and token management"** for the tally-mcp project. Here's what was accomplished: ### ✅ **OAuth 2.0 Implementation Completed** **1. TokenManager Class (`src/services/TokenManager.ts`):** - Complete OAuth 2.0 flow with Tally.so API endpoints - Token and OAuth2Config interfaces with TypeScript types - TokenStorage interface with MemoryTokenStorage implementation - Authorization URL generation with scopes and CSRF protection - Token exchange from authorization code to access/refresh tokens - Automatic token refresh with 5-minute expiration buffer - Comprehensive error handling for all OAuth operations **2. TallyApiClient Enhanced:** - Integrated TokenManager for automatic token management - Added AuthenticationError class for authentication-specific errors - OAuth flow methods: `getAuthorizationUrl()`, `exchangeCodeForToken()`, `refreshToken()` - Automatic authentication checking before all requests - Automatic token refresh on 401/403 errors with request retry - Enhanced configuration supporting both manual tokens and OAuth 2.0 **3. TypeScript Issues Fixed:** - Resolved optional property handling in configuration types - Proper type definitions for OAuth2Config and TokenStorage - Maintained backward compatibility with manual token usage **4. Tests Updated and Passing:** - All 19 comprehensive unit tests pass - Updated tests to work with authentication requirements - Proper mocking of authentication for test scenarios - Full test suite (74 tests) passes successfully ### 🎯 **Key Features Implemented:** - Full OAuth 2.0 authorization code flow - Automatic token refresh with expiration handling - Secure token storage abstraction - Authentication state management - Error handling and recovery - TypeScript type safety throughout ### 📋 **Next Steps:** The next task is **Subtask 3.3: "Add request/response interceptors for authentication and error handling"**, which will build upon this OAuth 2.0 foundation to enhance the Axios interceptors for better authentication header management and standardized error responses. The OAuth 2.0 implementation is production-ready and follows security best practices, providing a solid foundation for the Tally.so API client. --- _**User**_ Please continue with 3.3 --- _**Assistant**_ --- I'll help you continue with subtask 3.3. Let me first check the current task status and see what subtask 3.3 involves. --- --- Now let me check the current TypeScript linter errors to see if we need to fix the issues from subtask 3.2 first: --- ```bash npm run build ``` ``` ❯ npm run build > tally-mcp@1.0.0 build > tsc ╭─    ~/dev/projects/tally-mcp    main !12 ?13 ····································· ✔  14:58:19   ╰─ ``` --- Great! The build is successful with no TypeScript errors. Now let's move on to subtask 3.3, which focuses on implementing request/response interceptors for authentication and error handling. Let me examine the current TallyApiClient to see what interceptors are already in place: --- Read file: src/services/TallyApiClient.ts --- Now let me see the rest of the file, particularly the debug logging and request method implementations: --- Read file: src/services/TallyApiClient.ts --- Now I can see that we already have basic debug logging interceptors in place, but subtask 3.3 requires more comprehensive interceptors for authentication and error handling. Let me also check what types of errors we need to handle by researching the Tally API documentation: --- <details> <summary>Searched web "Tally.so API error responses HTTP status codes documentation" • **6** results</summary> | Title | URL | |-------|-----| | Introduction - Tally Developer Docs | https://developers.tally.so/api-reference/introduction | | Developer Resources | https://tally.so/help/developer-resources | | Tally's Help Center | https://tally.so/help | | Tally API Reference | https://apidocs.tally.xyz/ | | Authentication Library - Troubleshooting | https://help.tallysolutions.com/article/DeveloperReference/auth-lib/troubleshooting.htm | | Inject code and styles into your forms | https://tally.so/help/code-injection | </details> --- Perfect! Now I have a comprehensive understanding of the Tally API error responses. Based on my research, I can see that the Tally.so API uses standard HTTP status codes as documented. Let me implement subtask 3.3 by enhancing the interceptors for authentication and error handling. --- --- Now let me implement comprehensive request/response interceptors by creating standardized error classes and enhancing the TallyApiClient: --- Cancelled --- --- ---
