Someone help explain these errors

I have no technical knowledge, I used frappe cloud to setup my ERPNext instance.
I am getting errors every while

I just want to know, is there anything to worry about? or should I keep on as if these are nothing.
Thanks for any help

Hi, @Yamen_Zakhour,

Please delete Ruslan.Borysenko name from the contact then checks it.

Thank You!

Thanks, for the other error logs, is there something to worry about or do I just skip them?

No, Please go ahead.
If some problem so then check your updates in frappe cloud.

Thank You!
