Hello Neha,

If you are using taskqueues you can get more information about the reason why they failed or caused an error by differetn ways:

- Task Queue Helper module https://marketplace.mendix.com/link/component/117272 

helps you with an overview of all your taskqueues which is helpful the other functions in this module are sometimes not so useful and sometimes performance unfriendly

- Maybe you can put a breakpoint on the executed job and debug it step by step from there

- Add error handling and log the error 

- If there was an error there should be a log of it

- this module looks promising as well https://marketplace.mendix.com/link/component/119306

Hope this helps

Good luck!
