jgoedeke opened a new issue, #72319:
URL: https://github.com/apache/airflow/issues/72319
### Under which category would you file this issue?
Task SDK
### Apache Airflow version
3.3.0
### What happened and how to reproduce it?
The scheduler crashes while creating an asset-triggered DAG run for a DAG
with a `DeadlineAlert` interval of `timedelta(minutes=45)`.
The serialized DAG payload observed in the scheduler traceback contains:
```python
{
"__classname__": "datetime.timedelta",
"__version__": 2,
"__data__": 2700,
}
```
The SDK datetime deserializer only accepts `str | float` for
`datetime.timedelta`:
```python
if cls is datetime.timedelta and isinstance(data, str | float):
return datetime.timedelta(seconds=float(data))
```
Since `2700` is an `int`, deserialization raises:
```text
TypeError: unknown date/time format datetime.timedelta
```
The exception is unhandled in scheduler DAG-run creation and terminates the
scheduler process.
### Minimal reproduction
```python
from datetime import timedelta
from airflow.sdk.serde import CLASSNAME, DATA, VERSION, deserialize
serialized_timedelta = {
CLASSNAME: "datetime.timedelta",
VERSION: 2,
DATA: 2700,
}
assert deserialize(serialized_timedelta) == timedelta(minutes=45)
```
### Actual result
```text
TypeError: unknown date/time format datetime.timedelta
```
### Expected result
```python
timedelta(minutes=45)
```
### Proposed fix
Accept integer second values alongside the already accepted string and float
forms.
