Error: Cannot read properties of undefined (reading 'links')

Ghassan T.Jul 31 2025

Hi,

I'm getting the above-mentioned error starting from version 24.3.0. Previous version works with no issues.

I don't use VS Code often, but I did set it up some time ago and tested it and it was working fine. When the MCP Server was introduced a couple of weeks ago, I updated the extension and started getting this error. I tried all solutions I came across anywhere with no success, so I downgraded to last year's version and found that 24.2.1 is working, and with next version (24.3.0) I get this error.

I'm using the same connection in both cases, and it's a basic connection not TNS.

I'll include the logs form both.

Any help would be much appreciated.

Cheers,
