Timed out waiting for device using btrfs LUKS

After fresh installation using btrfs file system + LUKS. I can't boot in system with dropping in emergency shell.

I checked my FSTAB, it's good.

Here's the fstab file- [https://termbin.com/mc5f]

Here's the grub file - [https://termbin.com/pqlr]

This is my partition setup - [https://termbin.com/ot69]

Re: Timed out waiting for device using btrfs LUKS

Ok, I got this to boot but swap is disabled.

journalctl -b | grep swap                                                               [141]

Did you format the partition with mkswap?

Re: Timed out waiting for device using btrfs LUKS

This is my partition scheme- I want an encrypted swap-

This is what I did-

sgdisk --clear \
         --new=1:0:+550MiB --typecode=1:ef00 --change-name=1:EFI \
         --new=2:0:+8GiB   --typecode=2:8200 --change-name=2:cryptswap \
         --new=3:0:0       --typecode=3:8300 --change-name=3:cryptsystem \
           $DRIVE

# cryptsetup open --type plain --key-file /dev/urandom /dev/disk/by-partlabel/cryptswap swap
# mkswap -L swap /dev/mapper/swap
# swapon -L swap

Re: Timed out waiting for device using btrfs LUKS

Does it work when you do it manually?

Jan 23 10:45:45 arif swapon[412]: swapon: /dev/sda2: read swap header failed

Shouldn't it say swapon /dev/mapper/swap? It looks like it's trying to swap on the container.
