luks2john not working with my sha256 LUKS settings

I'm trying to attack LUKS header for an assignment. I have to use john and I need to crack the sha256 hash.

I made a virtual partition using dd to simulate a storage device on Kali. I encrypted it with LUKS1 using PBKDF2 as the PBKDF with force iterations and any other parameter as default.

This is my LUKS command:

cryptsetup luksFormat --type luks1 --pbkdf pbkdf2 --pbkdf-force-iterations 100000 image_file_name.img 

I try to extract the LUKS header with luks2john into a .txt file:

/usr/bin/luks2john image_file_name.img > txt_file_name.txt 

but I get the error:

.../(File path) : Only cbc-essiv:sha256 mode is supported. Used mode :b'xts-plain64\x00.......' 

So I try using the aes-cbc-essiv:sha256 as the cipher:

cryptsetup luksFormat --type luks1 --key-size 256 --cipher aes-cbc-essiv:sha256 --hash sha256 --pbkdf pbkdf2 --pbkdf-force-iterations 100000 image_file_name.img 

but I get the error:

.../(File path) : Only sha1 hash is supported. Used hash: b'sha256\x00......' 

I've tried to update John through git and clone it directly, but it still doesn't work.
