Describe the bug Since Chainlit 2.8.5, I now get Thread {thread_id} not found

To Reproduce .env CHAINLIT_AUTH_SECRET="Your secret" CUSTOM_AUTH=true

Frontend:

window.mountChainlitWidget({ chainlitServer: "http://127.0.0.1:8000", // Your Chainlit backend endpoint accessToken: accessToken, // Pass your generated JWT token theme: "light", customCssUrl: "http://127.0.0.1:8000/public/custom.css", expanded: false });

Full error:
