automount is broken after upgrading MacOS Monterey

I'm having issues with automount with my NFS shares after upgrading to MacOS Monterey 12.3.1. /etc/auto_master:

`
#
# Automounter master map
#
/System/Volumes/Data/mnt auto_mounts
+auto_master            # Use directory service
#/net                   -hosts          -nobrowse,hidefromfinder,nosuid
/home                   auto_home       -nobrowse,hidefromfinder
/Network/Servers        -fstab
/-                      -static

` /etc/auto_mounts

`
nas         10.17.24.105:/homes/mynas

`

`
$ sudo automount -vc
automount: /System/Volumes/Data/mnt mounted
automount: /System/Volumes/Data/home updated (/home -> /System/Volumes/Data/home)
automount: no unmounts
$ ls -l /System/Volumes/Data/mnt/
total 0
ls: fts_read: Input/output error

` Any ideas? I have already tried a bunch of things, including manually mounting the shares with mount -t nfs.
