Couldn't reproduce the issue. cc @dabasov @boddumanohar

Hi @iamrz1, Thanks for checking this.

the error seems to be coming from here:

https://github.com/0chain/gosdk/blob/85a1b96edabcf9ba31cc5be9e45ef134728cd349/zcncore/transaction_base.go#L661-L662

But I am lately not seeing this error. Will re-open this if I see the issue.
