I have an error message when I run a tuning process:

tuner <- mlr3tuning::tnr("mbo")
    instance <- mlr3tuning::ti(task = task,
                                             learner = mlr3tuningspaces::lts(mlr3::lrn("classif.rpart", predict_type = "prob")),
                                             resampling = mlr3::rsmp("spcv_coords", folds = 5) ,
                                             measures = mlr3::msrs(c("classif.auc", "classif.ce")),
                                             terminator = mlr3tuning::trm("evals", n_evals = 20))

OptimInstanceMultiCrit is deprecated. Use OptimInstanceBatchMultiCrit instead.

tuner$optimize(instance)

Error in private$.optimizer$optimize(inst) : 
  attempt to apply non-function

Is it no longer possible to use the ti() function?
