Python vs ruby AES PBKDF2

Question

I have a working python AES-256-GCM snippet from https://stackoverflow.com/a/77376155/22814155:

from Crypto.Cipher import AES
from Crypto.Hash import SHA512
from Crypto.Protocol.KDF import PBKDF2

# plaintext='Changeit!'
password='1+LFssX4whxz9lOPQ9OS7g4NvQzbCe8j'
salt = b'NiFi Static Salt'

def decrypt(ciphertext, key, mode):
  (ciphertext, authTag, nonce) = ciphertext
  encobj = AES.new(key,  mode, nonce)
  return(encobj.decrypt_and_verify(ciphertext, authTag))
  
key = PBKDF2(password, salt, 32, count=160000, hmac_hash_module=SHA512) # 32 bytes key
ciphertext = (
    bytes.fromhex('2242e26ffd3e2c33c2'),                # actual ciphertext 
    bytes.fromhex('98f06730fffa9687cb0d845f57c1a645'),  # authentication tag
    bytes.fromhex('697a84312aac99fbe2315f0637c96035')   # nonce
) 

res = decrypt(ciphertext, key, AES.MODE_GCM)
print ("\n\nDecrypted:\t",res.decode()) # Decrypted:   Changeit!     

However, I'm attempting to translate this to Ruby. I have the following code:

require 'openssl'

password = '1+LFssX4whxz9lOPQ9OS7g4NvQzbCe8j'
salt = 'NiFi Static Salt'

def decrypt(ciphertext, auth_tag, key, nonce)
  password = '1+LFssX4whxz9lOPQ9OS7g4NvQzbCe8j'
  salt = 'NiFi Static Salt'.bytes.join('')
  decipher = OpenSSL::Cipher.new('AES-256-GCM')
  decipher.decrypt
  decipher.key = key
  decipher.iv = nonce
  decipher.auth_tag = auth_tag

  decrypted_text = decipher.update(ciphertext)
  decrypted_text << decipher.final
  decrypted_text
end

key = OpenSSL::PKCS5.pbkdf2_hmac(password, salt, 160000, 32, 'SHA512')
ciphertext = ["2242e26ffd3e2c33c2"].pack('H*')                      # actual ciphertext
auth_tag = ["98f06730fffa9687cb0d845f57c1a645"].pack('H*')        # authentication tag
nonce =   ["697a84312aac99fbe2315f0637c96035"].pack('H*')         # nonce

res = decrypt(ciphertext, auth_tag, key, nonce)

puts "\n\nDecrypted:\t#{res}"

However, it errors with /tmp/test.rb:12:in iv=': iv must be 12 bytes (ArgumentError). The nonce is definitely larger than 12 bytes, however it was in python as well. Not sure what the difference is or how to correct it.
