Problems formating data (biomod2)

I keep running into an error while trying to run the BIOMOD_FormatingData()-function.

I have checked through all arguments and removed any NA-values, the explanatory variables are the same for both the testing and training datasets (independent datasets), and I've generated pseudo-absence data for the evaluation dataset (included in eval.resp.var).

Has anyone run into this error before? and if so, what was the issue related to? This is my first time using Biomod2 for ensemble modelling and I've run out of ideas as to what could be causing this error!

Here is my script and the subsequent error:

library(biomod2)

geranium_data <- 
        BIOMOD_FormatingData(
                resp.var = SG.occ.train['Geranium.lucidum'],
                resp.xy = SG.occ.train[, c('Longitude', 'Latitude')],
                expl.var = SG.variables, 
                resp.name = "geranium_data",
                eval.resp.var = SG.test.data['Geranium.lucidum'], 
                eval.expl.var = SG.variables, 
                eval.resp.xy = SG.test.data[, c('Longitude', 'Latitude')], 
                PA.nb.rep = 10, 
                PA.nb.absences = 4650, 
                PA.strategy = 'random',
                na.rm = TRUE
        )
