The error occurs because the stacks model is trying to predict values from columns that do not exist in the test dataset. This happens when the values_from argument in the predict function is set to a column range that includes a non-existent column. To solve this issue, you need to ensure that the values_from argument only includes existing columns in the test dataset. You can do this by using the select function from the tidyr package to subset the data before predicting values.
