Describe the Bug

Hi all,

The Snowflake SQL Language Server dies seconds after startup with:
<TypeError [ERR_INVALID_ARG_VALUE]: The argument ‘filename’ must be a file URL object…>

This happens every time I try to run a query.

Environment:
OS : Windows 11
Cursor : tried latest (0.51.x, Electron 30 / Node 20) and 0.47.3 (Electron 28 / Node 18)
Snowflake extension : 1.16.0-universal (last updated 2025-06-27)
Node inside extension host : 18.18.2 on the old Cursor build, 20.19.0 on the current one.

I’ve tried to update the extension to 1.16.0, theres no newer VSIX available.

Stuck and out of ideas, any help is appreciated.

Steps to Reproduce

  1. Start Cursor 0.51.x (latest) or 0.47.3.
  2. Install/enable Snowflake v1.16.0-universal (the only version visible in the marketplace).
  3. Open and run any .sql file

Operating System

Windows 10/11

Current Cursor Version (Menu → About Cursor → Copy)

Google:
“vs code can I roll back an extension update?”

Rolling back Snowflake extension to version 1.15.1 fixed things for me.
