I have timer job which creates new list item in custom list and then add attachment to the list item. It works perfectly fine but it threw one error once and there is no exception message in logging and only stack trace which leaves me guessing issue, typical microsoft stack traces :(.
Below is the stack trace, please help me to get the reason.
System.Runtime.InteropServices.COMException: <nativehr>0x80131904</nativehr><nativestack></nativestack>, StackTrace:

Edit 1: Even after getting this error list item got added into list but attachment did not.
