Is there an existing issue for this?

I have searched existing issues and this bug hasn't been reported yet

Current behavior

Since version 2025.2 proxy interceptor is not working anymore.

Steps to reproduce

Go to https://hoppscotch.io/
Select proxy interceptor in settings
Send a request to any URL (except echo.hoppscotch.io)
It fails with network_fail

Logs and Screenshots

Environment

Production

Hoppscotch Version

Cloud

Interceptor

Proxy - Web App

Browsers Affected

Not browser-specific

Operating System

MacOS

Additional Information

It seems to fail because RESTResponse.toResponse expects a Uint8Array and gets an ArrayBuffer.
