R help - Dec 2020 - Fwd: Error in setting the parameter values of k

I am using mlr3 'fast nearest neighbor' leaner i.e. fnnIts parameter is
'k' which has a default value of 1. When I use tuningusing random
search, I set the parameter of k as: lower= 0, upper=3But it gives an error
messageError in self$assert(xs) :  Assertion on 'xs' failed: k: Element
1 is not >= 1.I have tried different values but the error remains.Warm

I know absolutely nothing about the specific statistical tools being used here,
but:?

In several nearest neighbor routines, the parameter k refers to the number of
nearest neighbors to be considered (in some computation).? In that case, k must
be at least 1, which is what the cited error message seems to be claiming.? Are
you certain that k = 0 is a legitimate setting?

Thank you for your response.

 Are you certain that k = 0 is a legitimate setting?

Since, the default value of k is 1, I wanted to search between the values
of 0 to 3.

Milne, Do you mean I have to provide both the lower and upper bounds
greater than 1 in order to get rid of this error?
