Did some investigation on this one. This issue is not applicable only to AWS
secrets manager but is a general issue with any secrets backend, because of a
bug in Variable.get().
Set up a `airflow.secrets.local_filesystem.LocalFilesystemBackend` and
checked with both Airflow 2 and Airflow 3.
var.json
```
{
"A": "{\"num1\": 23, \"num2\": 42}"
}
```
Dag used:
```
from __future__ import annotations
from airflow.models import Variable
from airflow.models.baseoperator import BaseOperator
from airflow import DAG
# from airflow.sdk import Variable
class CustomOperator(BaseOperator):
def execute(self, context):
v = Variable.get(key="A")
print("Got value", v, type(v))
v1 = Variable.get(key="A", deserialize_json=True)
print("Got value from deser", v1, type(v1))
with DAG("get-var-sdk", schedule=None, catchup=False) as dag:
CustomOperator(task_id="set_var")
```
Airflow 2:
```
# With secrets backned
# [2025-05-20, 16:38:47 IST] {logging_mixin.py:190} INFO - Got value
{"num1": 23, "num2": 42} <class 'str'>
# [2025-05-20, 16:38:47 IST] {logging_mixin.py:190} INFO - Got value from
deser {'num1': 23, 'num2': 42} <class 'dict'>
```
Airflow 3:
```
[2025-05-21, 15:35:41] INFO - Got value {"num1": 23, "num2": 42} <class
'str'>: chan="stdout": source="task"
[2025-05-21, 15:35:41] INFO - Got value from deser {"num1": 23, "num2": 42}
<class 'str'>: chan="stdout": source="task"
```
As observed the second print for Airflow 3 is a string when it should really
be a dictionary.
