Our production app has suddenly stopped rendering the Login page, Dashboard, and User Profile after a recent frontend push. I need you to pull the latest code, reproduce the issue locally or in a staging branch, trace the fault through the React components, and implement a clean fix. Although the symptoms are on the React side, the project runs on a Python backend (deployed on AWS), so you may need to follow a request all the way through to confirm nothing server-side is silently failing. If the investigation uncovers any backend contribution to the problem, patch it as well and include a succinct explanation. I’m ready to give you repo access immediately. Tell me your earliest start time and an estimate for how long this level of bug normally takes you—speed matters, but I value a thoughtful, well-documented solution. Deliverables: • Functional Login, Dashboard, and User Profile pages rendering without errors • All submitted data processed and persisted correctly • Git commit(s) with clear comments, plus a brief changelog that highlights what was fixed and why Acceptance criteria: deploying your fix to staging shows no console errors, no failed network requests, and the three pages load in under two seconds each.
