   I faced the same issue with [airflow 2.3.0rc2](https://github.com/apache/airflow/tree/2.3.0rc2)
   Had a basic dag added.
   ```py
   from datetime import datetime
   from airflow import DAG
   
   from airflow.decorators import task
   
   with DAG(dag_id="map-reduce", start_date=datetime(2022,4,22)) as dag:
   
       @task
       def add_one(x: int):
           return x + 1
   
       @task
       def sum_it(values):
           total = sum(values)
           print (f"Total was {total}")
       
       added_values = add_one.expand(x=[1,2,'a'])
       sum_it(added_values)
   
       added_values_correct = add_one.expand(x=[1, 2, 3])
       sum_it (added_values_correct)
   ```
   
   Added scheduler logs in attachments.
