Client received "no session ID or not initialization request" when server restart #1476
How can the server request the client to re-initialize when server restart?
The client is currently experiencing a recurring server error from "no session ID or not initialization request".
We're seeing something similar... I'm noticing MCP servers on Claude Desktop are NOT re-using the same Session ID and they are generating a new one over and over again when interacting with a Cloudflare worker based MCP deployment. This is affecting a few of our customers (we work for MCPcat).
