Disable dash instance created before running dash project on dataiku

Hello,

I have developped a dash web-app using Dash packag, and it works well locally. However, once I have uploaded it to Dataiku, it is not working as expected.

My question is: how should I remove the "app = dash.Dash(...)" instance defined in dataiku? Is there a way to disable it and enable the dash instance declared in my codes?

dataiku-project/
├── app.py
├── dashboard/
│   ├── assets/
│   │   └── Icon.svg
│   ├── content.py
│   ├── index.py
│   └── layout/
│       ├── callbacks/
│       │   └── displayPageCallbacks.py
│       └── dataUpload.py
├── environment.yml
├── Procfile
└── README.md

In the `index.py` file, there is an dash instance created already:

# index.py
from dash import Dash
import dash_bootstrap_components as dbc

external_stylesheets = [dbc.themes.BOOTSTRAP]
app = Dash(
    __name__,
    suppress_callback_exceptions=True,
    external_stylesheets=external_stylesheets,
)
app_title = "My Project"
app.title = app_title

and this instance will be called for each other elements to compose our dashboard, for example "@app.callbacks(...)" in the other files.

Locally, we just need to run the `app.py` file:

# app.py
from dashboard.content import app


server = app.server
if __name__ == "__main__":
    app.run_server(debug=True)

which will call the app from the content.py with "app.layout" defined there:

# content.py
from dashboard.index import app
from dashboard.layout.callbacks import displayPageCallbacks
from dash import html, dcc, Input, Output
import dash_bootstrap_components as dbc

navbar = dbc.NavbarSimple(
    children=[
        dbc.NavItem(dbc.NavLink("Home", href="/")),
        dbc.NavItem(dbc.NavLink("Data upload", href="/data_upload")),
    ],
    brand="My Project",
    color="dark",
    dark=True,
    className="mb-2",
)

app.layout = html.Div(
    [
        dcc.Location(id="url", refresh=False),
        navbar,
        dbc.Container(id="page-content", className="mb-4", fluid=True),
    ]
)
