@DrAuYueng Thanks for the PR - before we can merge you'll need to sign the CLA to make the bot happy.

Is this in service of some other goal? Or just something you noticed? I would expect this error to always be the same thing, so not especially useful to log out.

@caseydavenport IMO, Err is defined and should not be swallowed in the subsequent processing, so err seems meaningless, for example:

if b.Allocations[ordinal] != nil {
		return cerrors.ErrorResourceAlreadyExists{
			Err:        fmt.Errorf("Address already assigned in block"),
			Identifier: address.String(),
		}
}
