libevdev_uinput_create_from_device failed: No such file or directory

Hi, recently (don't know exactly when), I'm getting the following error in uinput:

systemctl status udevmon.service

My service unit file:

systemctl cat udevmon.service
# /usr/lib/systemd/system/udevmon.service
[Unit]
Description=udevmon
Wants=systemd-udev-settle.service
After=systemd-udev-settle.service

[Service]
ExecStart=/usr/bin/nice -n -20 /usr/bin/udevmon -c /etc/udevmon.yaml

[Install]
WantedBy=multi-user.target

I'm using ArchLinux (up to today) with the following packages:

pacman -Ss libevdev     
extra/libevdev 1.8.0-1 [installed]
    Wrapper library for evdev devices

pacman -Ss yaml-cpp
community/yaml-cpp 0.6.3-1 [installed]
    YAML parser and emitter in C++, written around the YAML 1.2 spec

yay -Ss interception-tools  
aur/interception-tools 0.1.1-7 (+9 0.16%) (Installed)
    A minimal composable infrastructure on top of libudev and libevdev

yay -Ss interception-caps2esc
aur/interception-caps2esc 0.1.3-2 (+9 0.12%) (Installed)
    caps2esc: transforming the most useless key ever in the most useful one

My udevmon.yaml:

- JOB: 'intercept -g $DEVNODE | caps2esc | uinput -d $DEVNODE'
  DEVICE:
    EVENTS:
      EV_KEY: [KEY_CAPSLOCK, KEY_ESC]

I already reinstalled the packages and restarted the service, any ideas?

Thanks

EDIT: I'm trying to run uinput manually like:

uinput -p -d /dev/input/by-path/pci-0000:00:14.0-usb-0:3:1.0-event-kbd
