Hello, I am using airflow 2.0.2, I am trying the following code, and it
gives me this error. I have calling the function get_activated_sources from
python operator. I am trying to pass the values to the next sql fille.
Not sure if it's normal in airflow 2.0.2.
def get_activated_sources():
```
PostgreConn = PostgresHook(postgres_conn_id='redshift', schema='reports')
db_conn = PostgreConn.get_conn()
cursor = db_conn.cursor()
cursor.execute("SELECT id_pais, nombre, codigo, paisplataforma,
pais_longitud, pais_latitud, nombre_eng FROM mstr_new.dw_lu_pais;")
return cursor
```
**Error**
`[2021-05-20 07:04:27,350] {xcom.py:237} ERROR - Could not serialize the
XCom value into JSON. If you are using pickles instead of JSON for XCom, then
you need to enable pickle support for XCom in your airflow config.`
