Agniva De Sarker 94d09e1336 Fix return nil (#15330) ...

* Fix return nil

A nil error is an interface having nil value but a non-nil type.
This leads to unexpected errors in the code well-documented here:
https://golang.org/doc/faq#nil_error

We fix this by passing an additional parameter to handle it.
