> [Go SDK] Empty side inputs causing spurious zero elements

> A user discovered that empty side inputs would spuriously provide a single
> zero element.
> The error was narrowed down to the Go SDK's state manager code copying the
> stateGetResponse data wasn't checking that the original data source even had
> any bytes in it, leading it in particular to interpret length prefixed data
> as having 0 length, which would cause zero value elements to be generated.
> Notably, this caused empty strings.
