Streamable HTTP error - Session not found #1360
Description
Describe the bug
I can successfully add and start using MCP. However, after a while, MCP calls start consistently failing with an error.
Streamable HTTP error: Error POSTing to endpoint: {"error":{"code":-32001,"message":"Session not found"},"id":"","jsonrpc":"2.0"}
Exit / resume of Copilot CLI mitigates the issue but is annoying.
Affected version
