No fix: ASP.NET error unrelated to this Python repository

[Copilot]

The reported 500 error from /favicon.svg (System.ArgumentOutOfRangeException in SendFileAsync) originates from an ASP.NET Core application (ITHCWY middleware at C:\GitHub\ithcwy-core\ITHCWY\), not this Python voice assistant project.

Investigation Summary

• This repository contains only Python code—no .cs, .csproj, or ASP.NET middleware
• No favicon.svg exists in this codebase
• The stack trace explicitly references a different project/path

For the actual ITHCWY project

The error indicates stale static asset metadata (reported size vs actual file size mismatch). Typical fix:

• dotnet clean && dotnet build to regenerate *.staticwebassets.endpoints.json
• Verify favicon.svg file size matches the asset descriptor

Original prompt

I'm getting the following 500 error logged from a request to /favicon.svg which exists and seems to serve with no issues. Investigate and suggest a fix.

System.ArgumentOutOfRangeException: (Parameter 'count')
Actual value was 698.
