> claude fix the authentication error in our login flow

I'll investigate the auth error. Let me look at the relevant files.

‍

Examining auth-related files...

* src/services/authService.js

* src/components/Login.jsx

* src/store/authSlice.js

‍

Running the login flow...

‍

Error detected: "401 Unauthorized: Token expired"

‍

Root cause:

* Token refresh mechanism not handling expired tokens correctly

* Refresh token missing from request header

* Improper error handling for 401 responses

‍

Updating authService.js with proper refresh logic...

Updating request interceptor for 401 handling...

Testing the fix...

‍

* Login successful ✓

* Token refresh working ✓

* Proper redirection on expired tokens ✓

‍

Authentication error fixed! The login flow now properly handles token expiration.

Developers love Claude

“I taught a friend who has never written code in her life how to use Claude to build a simple app and deploy it on Cloudflare today. Watching someone realize that they can now build software is a great experience. Enable everyone to build anything.”

Logan Grasby, @LoganGrasby

“I introduced someone to Claude Code, Opus last night, and we were up til 4 am building a project. It was crazy! 20K lines of codes, audit logging, a full Prisma Database, complete architecture, and a complete roadmap with 4 phases for complete implementation.”

Teneika Askew, @teneikaask_you

“Just taught my fiancée how to use claude to write code that automates dumb tasks that have been making her work life miserable for months. She went from being downtrodden and skeptical to dancing around the room in about 15 minutes. END USER PROGRAMMING IS NOW.”

Kasey, @kaseyklimes

“I know this sounds cringe, but I literally have clammy hands and a racing heart because of how powerful Claude + Cursor is. Like I just made a whole new feature, frontend and backend, built on top of my own custom APIs without touching code, then I had it switch from a SwiftUI.”

Majd Taby, @jtaby

“Anthropic is leading the Industry with models - like Sonnet and Opus - and developer tools - like Claude Code.”

Jon Meyers, @jonmeyers_io

“With new Claude i officially feel like a fraud when i code, I’m the guy in the corner saying um nice job boss keep going.”
