[Solved] Won't boot system running LVM on LUKS on RAID

Hi, in my new system I'm using LVM on LUKS on RAID. This is visualised below.

NAME               MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINT
sda                  8:0    0 223.6G  0 disk  
|-sda1               8:1    0     1G  0 part  /boot
`-sda2               8:2    0 222.6G  0 part  
  `-md127            9:127  0 444.9G  0 raid0 
    `-ssdraid0enc  253:0    0 444.9G  0 crypt 
      |-ssdVG-swap 253:1    0    16G  0 lvm   
      |-ssdVG-root 253:2    0    96G  0 lvm   /
      `-ssdVG-home 253:3    0 299.6G  0 lvm   /home
sdb                  8:16   0 223.6G  0 disk  
|-sdb1               8:17   0     1G  0 part  
`-sdb2               8:18   0 222.6G  0 part  
  `-md127            9:127  0 444.9G  0 raid0 
    `-ssdraid0enc  253:0    0 444.9G  0 crypt 
      |-ssdVG-swap 253:1    0    16G  0 lvm   
      |-ssdVG-root 253:2    0    96G  0 lvm   /
      `-ssdVG-home 253:3    0 299.6G  0 lvm   /home

However the system won't boot and times out looking for /dev/ssdVG/root

I imagine it has something to do with my mkinitpcio image (https://ptpb.pw/Hb2c).
Also, here is my mdadm.conf file which is embedded in the initram when I use the mdadm_udev hook (https://ptpb.pw/ltOy)
And my /etc/default/grub file (https://ptpb.pw/x_sO)
The argument I am passing is cryptdevice=/dev/md/ssdraid0:ssdraid0enc
Are my hooks setup right? How do I debug this?

Thanks

Solution:
Need to use rd.luks.name rather than cryptdevice argument to kernel

Just to note cryptdevice is correct for the none sd hook,  rd.luks.name is correct for he sd hook.
