Joomla exception "throw new DebugBarException("Session must be started before using stack data in the debug bar");"

Question

I have updated my website to Joomla 4.13 and using Postman to get data via Joomla 4 webservices. I have turned on the Debug. Now I'm getting a response to the Postman "Session must be started before using stack data in the debug bar" and it turns out /libraries/vendor/maximebf/debugbar/src/DebugBar/DebugBar.php (line 447) throw new DebugBarException("Session must be started before using stack data in the debug bar"); is executing. Can anyone help me? Thanks
