TJaniF opened a new issue, #47832:
URL: https://github.com/apache/airflow/issues/47832
### Apache Airflow version
3.0.0
### If "Other Airflow 2 version" selected, which one?
3.0.0b3
### What happened?
I was attempting to pass data between @asset decorated tasks with the
following code:
```python
from airflow.sdk.definitions.asset.decorators import (
asset, # A
)
@asset(schedule="@daily") # C
def raw_quotes(): # D
"""
Extracts a random set of quotes.
"""
import requests # E
quotes = "Hello"
return quotes # F
@asset(schedule=raw_quotes) # A
def selected_quotes(quotes=raw_quotes): # B
"""
Transforms the extracted quotes.
"""
print(quotes)
```
After unpausing both generated dags I ran the raw_quotes dag, which
completes successfully, then triggers the selected_quotes dag.
This dag gets stuck in running state because the scheduler crashes with:
```
scheduler | File
"/Users/tamara.fingerlin/.pyenv/versions/3.12.8/lib/python3.12/multiprocessing/queues.py",
line 389, in get
scheduler | return _ForkingPickler.loads(res)
scheduler | ^^^^^^^^^^^^^^^^^^^^^^^^^^
scheduler | TypeError: ServerResponseError.__init__() missing 2 required
keyword-only arguments: 'request' and 'response'
scheduler | [2025-03-16 18:02:03 +0100] [74940] [INFO] Shutting down: Master
```
Full error log:

### What you think should happen instead?
Ideally the downstream asset should fetch the XCom returned from the
upstream asset. If I got the syntax wrong, the downstream asset should fail
with an error, without crashing the scheduler.
### How to reproduce
1. Add the code provided above
2. unpause both dags that are created
3. run the raw_quotes dag
4. see the error appear in the scheduler logs
