Airflow docker operator Internal Server Error ("b'Mounts denied: EOF'") MacOS - docker

Question

I'm trying to use the docker operator on an airflow pipeline. This is the code I'm using:
from airflow import DAG
from airflow.operators.bash_operator import BashOperator
from datetime import datetime, timedelta
from airflow.operators.docker_operator import DockerOperator
default_args = {
'owner' : 'airflow',
'description' : 'Use of the DockerOperator',
'depend_on_past' : False,
'start_date' : datetime(2018, 1, 3),
'email_on_failure' : False,
'email_on_retry' : False,
'retries' : 1,
'retry_delay' : timedelta(minutes=5)
}
with DAG('docker_dag', default_args=default_args, schedule_interval="5 * * * *", catchup=False) as dag:
t1 = BashOperator(
task_id='print_current_date',
bash_command='date'
)
t2 = DockerOperator(
task_id='docker_command',
image='alpine:3.7',
api_version='auto',
auto_remove=True,
command="/bin/sleep 30",
docker_url="unix://var/run/docker.sock",
network_mode="bridge"
)
t3 = BashOperator(
task_id='print_hello',
bash_command='echo "hello world"'
)
t1 >> t2 >> t3
The original source is: How to use the DockerOperator in Apache Airflow
I run my DAG using the airflow UI , but in the docker_command task I get this error:

Update: This exercise I did it on a Mac, but I tried to do the same on a Linux OS (Ubuntu 18.04 distribution) and everything is working fine. So, I'm afraid this is related with something about my configuration on macOS or the permissions I have on the computer.
On Mac I have Catalina version 10.15.5.
Do you have any idea why I'm getting that error?
