Mounting exfat with udev rules automatically

I'm trying to mount various SD cards automatically with udev rules. I started with these rules, solved a problem with the help of this question, and now I have the following situation:

ext4 and vfat formatted devices work perfectly, but when I plug in an exfat or an NTFS formatted disk I get the following line in mount:

/dev/sda1 on /media/GoPro type fuseblk (rw,nosuid,nodev,noatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096)

And the directory listing looks like this:

$ ls -l /media/
ls: cannot access '/media/GoPro': Transport endpoint is not connected
total 0
d????????? ? ? ? ?            ? GoPro

I can't do anything under that mountpoint, not even as root:

$ sudo ls -l /media/GoPro
ls: cannot access '/media/GoPro': Transport endpoint is not connected

The only problems I can find from other people with the error message Transport endpoint is not connected seem to happen after a disk wasn't unmounted properly. But I have the problem while the disk is mounted.

My current udev rules look like this:

KERNEL!="sd[a-z][0-9]", GOTO="media_by_label_auto_mount_end"
ACTION=="add", PROGRAM!="/sbin/blkid %N", GOTO="media_by_label_auto_mount_end"

# Do not mount devices already mounted somewhere else to avoid entries for all your local partitions in /media
ACTION=="add", PROGRAM=="/bin/grep -q ' /dev/%k ' /proc/self/mountinfo", GOTO="media_by_label_auto_mount_end"

# Global mount options
ACTION=="add", ENV{mount_options}="noatime"
# Filesystem-specific mount options
ACTION=="add", PROGRAM=="/sbin/blkid -o value -s TYPE %E{device}", RESULT=="vfat|ntfs", ENV{mount_options}="%E{mount_options},utf8,uid=1000,gid=100,umask=002"
ACTION=="add", PROGRAM=="/sbin/blkid -o value -s TYPE %E{device}", RESULT=="exfat", ENV{mount_options}="%E{mount_options},utf8,allow_other,umask=002,uid=1000,gid=1000"

# Get label if present, otherwise assign one
ENV{ID_FS_LABEL}!="", ENV{dir_name}="%E{ID_FS_LABEL}"
ENV{ID_FS_LABEL}=="", ENV{dir_name}="usbhd-%k"

# Mount the device
ACTION=="add", ENV{dir_name}!="", RUN+="/bin/mkdir -p '/media/%E{dir_name}'", RUN+="/bin/mount -o %E{mount_options} /dev/%k '/media/%E{dir_name}'"

# Clean up after removal
ACTION=="remove", ENV{dir_name}!="", RUN+="/bin/umount -l '/media/%E{dir_name}'"
ACTION=="remove", ENV{dir_name}!="", RUN+="/bin/rmdir '/media/%E{dir_name}'"

# Exit
LABEL="media_by_label_auto_mount_end"

I tried using user_id and group_id instead of uid and gid but to no avail.

Mounting the device manually works fine:

$ sudo mount -o noatime,utf8,allow_other,umask=002,uid=1000,gid=1000 /dev/sdb1 /media/GoPro/
FUSE exfat 1.2.5
$ ls -l /media/
total 132
