List variable serialized

[kyahia]

I have variables of type 'list in my BPMN. When I use get_variable() method I'm getting a serialized Java object. How can I convert it to a python list ?

exemple :

• On bpmn : my_var = [ "hello", "world" ]
• In python external task workder:
  print(task.get_variable('my_var')) => rO0ABXNyABNqYXZhLnV0aWwuQXJyYXlMaXN0eIHSHZnHYZ0DAAFJAARzaXpleHAAAAACdwQAAAACdAAHIndvcmxkInQAByJoZWxsbyJ4

print(base64.b64decode(task.get_variable('my_var'))) => b'\xac\xed\x00\x05sr\x00\x13java.util.ArrayListx\x81\xd2\x1d\x99\xc7a\x9d\x03\x00\x01I\x00\x04sizexp\x00\x00\x00\x02w\x04\x00\x00\x00\x02t\x00\x07"world"t\x00\x07"hello"x'

Hi, I had a similar issue with a JSON variable that contains a list of object. I needed to disable the deserializeValues so that Camuda passed the value as a JSON string.

client = ExternalTaskClient(
    worker_id,
    engine_base_url,
    config={
        "deserializeValues": False,
        ...
    },
)

It might be unrelated to your issue, but you can give it a try.
