issue loading daily seasonal

Expected Behavior

Trying to load seasonal daily data

Current Behavior

The recipe check is successful but I get an error when I call Loading()

Error in attr(x, "values") <- !flag : attempt to set an attribute on NULL

> recipe <- prepare_outputs(recipe_daily)

In addition: Warning messages:

2: ! Warning: Could not find any pattern dim with explicit data set descriptions (in

Possible Solutions?

I've traced back the error to this line in starR but I don't know what is causing it:

https://earth.bsc.es/gitlab/es/startR/-/blob/master/R/Start.R#L1316

tmp <- lapply(dat_selectors[which(dim_names != pattern_dims)], add_value_indices_flag)
