sarkch opened a new issue, #41918:
URL: https://github.com/apache/airflow/issues/41918
### Apache Airflow version
Other Airflow 2 version (please specify below)
### If "Other Airflow 2 version" selected, which one?
2.8.1
### 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
```
