The `...` are not used in this function but one or more objects were passed: 'preprocessor'

Does anybody knows- where this warning comes from?

The `...` are not used in this function but one or more  objects were passed: 'preprocessor'

I have no example code yet. I just gather ideas/informations.

Comes from passing undefined arguments to a function that doesn't support it via the elipsis argument (...).

So there is no conversation possible- including useful links.

Could it be...

tune_grid()

res <- do.call(tune_grid,list(
	modelObj 
	,preprocessor = preProc
	,resamples    = folds
	,param_info   = dials::parameters(modelObj)
	,grid         = tuningGrid
	,metrics      = metric
	,control      = control_grid(save_pred = TRUE)
))

...wondering why elipsis argument is in the middle of the function.

Try this

res <- do.call(tune_grid,list(
	object = modelObj   # needed a name!
	,preprocessor = preProc
	,resamples    = folds
	,param_info   = dials::parameters(modelObj)
	,grid         = tuningGrid
	,metrics      = metric
	,control      = control_grid(save_pred = TRUE)
))

I get the same warning...

res <- do.call(tune_grid,list(
	object        = modelObj   # needed a name!
	,preprocessor = preProc
	,resamples    = folds
	,param_info   = NULL
	#,param_info   = dials::parameters(modelObj)
	,grid         = tuningGrid
	,metrics      = NULL
	,control      = control_grid(save_pred = TRUE)
))

Warning message:

When I look at the documentation, it seems preprocessor is only an argument if object is a parsnip object. Is your modelObj a parsnip object or a workflow object? If it is the latter, then there should be no preprocessor argument.
