Hello Antigravity team,
I am currently using the latest version of Antigravity IDE on Windows, and I am entirely unable to use the Browser Agent / Web Session feature, especially after a fresh OS installation.
Description of the Issue:
When triggering the Browser Agent (via the UI or /browser command), the IDE attempts to download the Playwright driver using the Go library (ms-playwright-go). However, it specifically requests an outdated version (1.57.0) from the Microsoft Azure CDN.
Microsoft seems to have removed or relocated this specific .zip file from their CDN, resulting in a persistent HTTP 404 error. Because the download fails, the Browser Agent crashes and refuses to open.
Error Output / Logs:
The IDE attempts to download from this exact URL:
https://playwright-akamai.azureedge.net/builds/driver/playwright-1.57.0-win32_x64.zip
Result: HTTP 404 Not Found.
Environment Details:
- OS: Windows 11/10 (x64)
- Target folder created by IDE: C:\Users[Username]\AppData\Local\ms-playwright-go\1.57.0
- Antigravity Version: Latest (no updates available)
Steps to Reproduce:
- Start with a fresh Windows system (or clear the
%LOCALAPPDATA%\ms-playwright-gofolder). - Launch Antigravity IDE.
- Open a project and attempt to launch the Browser Agent (
/browser). - Watch the internal process fail with the 404 error from the CDN.
Suggested Fix:
The underlying playwright-go dependency in your codebase needs to be updated to a newer version (e.g., 1.61+) where the driver binaries are still actively hosted by Microsoft, or the download URL fallback needs to be patched.
Thanks in advance for looking into this!
