Encountered an unexpected error when processing the request, please try again When run /review command

## Problem
Every time I execute the `/review` command, no matter review the entire workspace or the active file. Q Dev tells me "Encountered an unexpected error when processing the request, please try again".

I checked the Amazon Q log, and here is the error msg

```

2025-02-05 20:42:49.150 [error] Security scan failed. 'Error: [UploadArtifactToS3Error]'
```

## Steps to reproduce the issue

1. Open the Chat Panel
2. type `/review` in the input box and select Review workspace

## Expected behavior

Review without prompting me the error msg.

## System details (run `AWS: About` and/or `Amazon Q: About`)

- OS: Darwin arm64 24.2.0
- Visual Studio Code version:1.96.4
- AWS Toolkit version: N/A
- Amazon Q version: 1.45.0

Start with the VS Code /review command and reproduce a workspace review using the reported Amazon Q version. Trace the security scan failure reported as UploadArtifactToS3Error and verify that both workspace and active-file reviews complete without the unexpected error.
