If there are more than 1 time triggered jobs configured in powerJobs Processor that are triggered at the same time they begin to fail with the error
2021-08-27 09:08:00,009 [DefaultQuartzScheduler_Worker-7] ERROR coolOrange.VaultServices.Vault.VaultServiceTryExtentions - Failed to add the job 'TimeTriggeredJob' to queue
System.NullReferenceException: Object reference not set to an instance of an object.

at coolOrange.VaultServices.Exceptions.Util.TryReturnException[TResult,TException](Func`1 func, TException& outException)
This issue is caused by the time triggered jobs trying to execute the same method at the same time
Change your *.settings file so that the jobs are triggered at least 10 seconds apart from another. for example one job should be triggered every minute and another job every 1:15 minutes.
