arch linux – Pacstrap -K fails with unhelpful error message

I hope I haven’t missed anything obvious and if you need more information I can supply it. I’m trying to manually install arch from a live usb to a secondary partition on my laptop. I’m using the most recent (as of writing) iso from the arch linux website.
I connected to the internet, formatted the partition (btrfs), mounted it to /mnt, and ran pacstrap -K /mnt base linux linux-firmware intel-ucode systemd iwd nano pacman. This failed with error: command failed to execute successfully. Does anyone know either how to fix this or enable logging so I know what went wrong? I attached a picture of the output.
