In general errors should either be logged or returned, but not both.
To quote Dave Cheney:
If you choose to handle the error by logging it, by definition it’s not an error any more — you handled it. The act of logging an error handles the error, hence it is no longer appropriate to log it as an error.

yes, totally make sense. Initially I wanted to print debug message, but I thought debug is not relevant here either. If error is not logged here with additional message, then it is a bit difficult to figure where the flow is aborted

I would wrap the returned error in fmt.Errorf with the same text from the log, and then have the caller log it.

yup, there are few other places where it needs to be changed, but probably will do it in next PR
