The same decryption code works in notebook, but fails in python file:

import gnupg
from pyspark.dbutils import DBUtils

dbutils = DBUtils(spark)

gpg = gnupg.GPG()

decryption_key = dbutils.secrets.get(secret_scope, secret_name)
gpg.import_keys(decryption_key)

input_file_path = f"/Volumes/{catalog}/{schema}/{volume}/{folder}/{file}.csv.pgp"

with open(input_file_path, 'rb') as f:
    encrypted_data = f.read()

decrypted_data = gpg.decrypt(encrypted_data)

if decrypted_data.ok:
    print("Ok")

So, in notebook it's Ok. But In python file I receive WARNING:gnupg:FAILURE status emitted from gpg process: decrypt 4294967295. And the decrypted_data is empty.
