Execution RecurringJobScheduler is in the Failed state now due to an exception

[mudasar]

Hello there,
I am facing this issue when running multiple servers with the same database. there are some recurring jobs which are stuck to a single server that was turned off. Is there a direct way to trigger these jobs manually?
Also, any solution to the following issue?

Execution RecurringJobScheduler is in the Failed state now due to an exception, execution will be retried no more than in 00:00:16 System.ArgumentException: An item with the same key has already been added. Key: LastExecution

What you can do is find the duplicate Hash entry for this recurring job and delete the older document.

select * from c where type = 6 and key = 'recurring-job-id'

Hi, @imranmomin thanks for your reply. I did fix it by going through the cosmos DB for recurring jobs that were a lot. This happens when you try to join an already running job queue server.

Is there a way we can avoid getting into this position at all ?

This broke for us too.
