[Python] Oracle Cloud : Issue to deploy python function using Cloud Shell

I want to create a python function with Oracle Cloud's function service. To do this, I'm following the Getting started tutorial using Cloud Shell Setup. I follow all the steps as indicated, but when I come to deploy the function with the command fn -v deploy --app DBDB_IO_Refresher. I get this error :

Fn: error running docker build: Cannot create/use builder instance docker for oci_fn_builder : exit status 125


Here are all the instructions I followed:

fn list context
fn use context eu-marseille-1
fn update context oracle.compartment-id ocid1.********************
fn update context registry ***********/func-python
docker login -u '***********' mrs.ocir.io
fn list apps
fn init --runtime java hello-test-python
cd hello-test-python
fn -v deploy --app DBDB_IO_Refresher


Here are the details of the error:
