Fix Automount Problem with exFAT Filesystem

I need some help to configure automount with exfat filesystem (no problem with ext4 for example).

$ sudo automount -f -v
$ ls /home/user/automount

Automount return this error.

mounted direct on /home/user/automount with timeout 120, freq 30 seconds
attempting to mount entry /home/user/automount
>> /sbin/mount.exfat: invalid option -- 's'
>> Usage: /sbin/mount.exfat [-d] [-o options] [-V] <device> <dir>
>> FUSE exfat 1.1.0
failed to mount /home/user/automount

Configuration files.

$ cat /etc/auto.master.d/removal.autofs 
/- /etc/auto.removal uid=1000,gid=1000,--timeout=120,--ghost

$ cat /etc/auto.removal 
/home/user/automount -fstype=exfat UUID=54E8-C318

Thanks for any help.
