URL: https://github.com/apache/airflow/issues/41843
### Apache Airflow Provider(s)
amazon
### Versions of Apache Airflow Providers
2.8.1
### Apache Airflow version
2.8.1
### Operating System
Managed Airflow
### Deployment
Amazon (AWS) MWAA
### Deployment details
_No response_
### What happened
I am using `StepFunctionStartExecutionOperator` to execute a StateMachine.
```
StepFunctionStartExecutionOperator(
...
task_id="load_data",
deferrable=True,
waiter_delay=30, # Poll for every 30 seconds
waiter_max_attempts=10, # maximum number of attempts to poll for status
do_xcom_push=True,
)
```
if I look into the log of the task,
```
{{waiter_with_logging.py:129}} INFO - Status of step function execution is:
{{waiter_with_logging.py:129}} INFO - Status of step function execution is:
{{waiter_with_logging.py:129}} INFO - Status of step function execution is:
```
as you can see that airflow is not getting the current status (RUNNING,
FAILED etc) of the StateMachine
### What you think should happen instead
Expected Output when the State Machine is RUNNING
```
[2024-08-28, 17:01:06 UTC] {{waiter_with_logging.py:129}} INFO - Status of
step function execution is: RUNNING
[2024-08-28, 17:02:06 UTC] {{waiter_with_logging.py:129}} INFO - Status of
step function execution is: RUNNING
```
### How to reproduce
So in my case I found the root cause of this problem. The IAM Role
associated with the Airflow did not have the below permission
```
'states:DescribeExecution'
```
On the StateMachine execution arn.
```
arn:aws:states:<Region>:<accountId>:execution:<stateMachineName>:*
```
### Before granting the permission
[2024-08-28, 01:41:53 UTC] {{waiter_with_logging.py:129}} INFO - Status of
step function execution is:
### After Granting the permission
```
[2024-08-28, 17:01:06 UTC] {{waiter_with_logging.py:129}} INFO - Status of
step function execution is: RUNNING
```
Unfortunately, MWAA does not throw `Accessdenied` permission error if the
IAM role does not have aforementioned permission on the execution arn of the
StateMachine.
