Resume Review still fails to parse AI response after model update

[Kienda]

Bug description

The Resume Review feature displays:

“Failed to parse the AI response.”

This is still occurring even though PR #892, which updated the retired Anthropic model, was merged into the main branch.

Steps to reproduce

1. Sign in to the ColorStack platform.
2. Open Resume Review.
3. Upload a valid PDF resume under 1 MB.
4. Click “Get Feedback.”
5. The application displays “Failed to parse the AI response.”

Expected behavior

The application should generate structured feedback for the resume bullet points or display an accurate error explaining why the request failed.

Actual behavior

No feedback is returned, and the interface displays a generic AI response parsing error.

Environment

• Operating system: Windows 11
• Browser: Google Chrome
• Feature: Resume Review
• File type: PDF under 1 MB

Additional context

PR #892 updated the retired Anthropic model to claude-sonnet-4-6, but the issue remains reproducible.

The current error may be hiding another failure, such as:

• Production deployment not containing the latest update
• Anthropic authentication, billing, or permission errors
• Invalid or incomplete structured AI output
• Schema validation failure
• Multiple backend errors being converted into the same generic message

I would be interested in investigating and submitting a fix if the maintainers approve.

I can reproduce this issue consistently and would like to investigate the root cause and submit a fix. May I be assigned to this issue?
