Error in na_locf(x, option, na.remaining, maxgap) : Input data has only NAs. Input data needs at least 1 non-NA data point for applying na_locf

Hi,

I am trying to use the calc_allHIT on modelled flow data in South Africa. This seems to run fine on some sets of data (stations), but gives the following error on others:

_Error in na_locf(x, option, na.remaining, maxgap) :
Input data has only NAs. Input data needs at least 1 non-NA data point for applying na_locf_

I have wracked my brain for almost a month now trying to figure out why I keep getting this error.

I am attaching my simplified R script and two data sheets (one that works and one that does not). I would greatly appreciate any insight into what may be causing this error.

Kind regards,
