Sessions are not implemented
Why does the sentry SDK client sometimes say Not Implemented: /api/1/envelope/ when used with GlitchTip?
Because tracking sessions are not implemented. There is no plan to implement sessions. If you would like to implement sessions, please justify the use case here and how you would approach it. If you don't wish to see these logs in your sentry sdk client, then disable session tracking.
