My cron expression is * * * * *
I am not able to find out why is it triggering Notify method twice every minute? Do I need to change the cron expression to */1 * * * *?
If I add the expression as 0 * * * * * it is failed to parse the expression and getting the below error
expected exactly 5 fields, found 6: [0 * * * * *]
