TupletUp or TupletDown not working for me

Question

On version 2.24.1, I'm trying to apply direction to my tuplets with \tupletUp and/or \tupletDown but it doesn't work. \tuplet 3/2 {...} is working fine but when I change it got this message:

error: syntax error, unexpected FRACTION
  \tupletUp 
            3/2 {...}

Yes, I can use \override as shown here but that's not my point

EDIT:

This is what I'm trying to achieve. Writing this I've found that \arpeggio works but \arpeggioUp doesn't. Related?)

Example Code:

\version "2.24.1"
\language "espanol"

\relative sol' {
  \key do \minor
  \time 5/4
  <fa' re'>2.  \tuplet 3/1 { re'4 mib8 re do re }
}

Output:

Using \tupletUp (as @jeanas suggests)

<fa' re'>2.  \tupletUp { re'4 mib8 re do re }

Produces:

As explained in a comment, \tupletUp and \tupletDown should be added but not replace \tuplet. The error message you get happens because \tupletUp stands on its own, and the next thing in your file is 3/2, which LilyPond doesn’t know how to interpret.

Note that \tupletUp will set the direction for all subsequent tuplets, but you can use \once \tupletUp to restrict it to one tuplet only.
