todev-disk-by\x2duuid.swap failed (according to systemctl )

I entered the following command into terminal and was surprised to receive

$ systemctl --state=failed
  UNIT                              LOAD   ACTIVE SUB    DESCRIPTION
● dev-disk-by\x2duuid-3ca23094\x2dc604\x2d467c\x2da125\x2dc4f292307545.swap load failed /dev/disk/by-uuid/3ca23094-c604-46

i looked to see if swap failed to load but it seems it loaded fine

 swapon -s

 journalctl -b | grep swap

[-@archBox ~]$ dmesg | grep swap

Here is my fstab

Swap seems to be loading fine ,but systemctl doesnt think so
Does anyone have any ideas on what could be causing this?
Any help would be very much appreciated !

hi
Can you read this in the wiki?

Re: todev-disk-by\x2duuid.swap failed (according to systemctl )

Thanks for the response!

Reading through the wiki article, I commented out swap from the fstab, which solved the issue, but I am a bit confused as to why

It says that there are 2 ways the swap partition is activated,
1. systemd-fstab-generator
   - Because this way reads the fstab file to activate swap , this executable spawned the failed process

2. systemd-gpt-auto-generator
  - This auto generates the swap based on the partition type (83)

the solutions seem to disable either one way other the other for the activating the swap?
Is the resulting failure in systemd the result of trying to activate swap twice?

how do you set the attribute of the swap partition to 63 ( are they referring to partition type in the solutions)?
