After a period of inactivity on the scheduler calendar users are getting a error popup when they try and access anything on the scheduler. The error states;
'There was an error in the callback.'
followed by a long string of random characters. This seems to be an error on the call back, its probably because the session is expired. I want to be able to catch this error to then potentially redirect them to login page if the session has expired but as it's a call back I'm struggling to be able to catch it. I've uploaded a screen shot of the full error pop up.
