reasonix: new session: %w

Error message

reasonix: new session: %w

What it means

Wraps a failed POST /new inside reasonix newSession (invoked when no session ID or the literal 'new' is passed): the remote serve instance refused or failed the request to create a fresh session. The session context is cancelled and StartSession surfaces the error.
