Dash resumable Upload in Multipage app displays blank page

Hi everyone,

Just one question, has anybody tried to use resumable upload component on multipage app?

I’m running into a problem when trying to do this, since I get blank page, no error on server.

below is the structure of the app I’ve tried - when I add in app1.py just some static content like html.H3(‘App 1’) app works fine and displays it on a screen but when I run it as presented below it shows only blank screen. I guess the problem is with dash_resumable_upload.decorate_server(app.server, “uploads”) component, maybe I’m placing it at the wrong place, or it requires another step or workaround? Any idea will be appreciated.

import dash

app = dash.Dash()
app.config.suppress_callback_exceptions = True

import dash_resumable_upload
import dash_html_components as html

layout = html.Div([
maxFileSize=102410241000, # 100 MB
textLabel=“Drag and Drop Here to upload!”,

import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output

from app import app
from apps import app1

import dash_resumable_upload
dash_resumable_upload.decorate_server(app.server, “uploads”)

app.layout = html.Div([
dcc.Location(id=‘url’, refresh=False),

@app.callback(Output(‘page-content’, ‘children’),
[Input(‘url’, ‘pathname’)])
def display_page(pathname):
if pathname == ‘/’:
return app1.layout
return ‘404’

if name == ‘main’:

I found a solution. The problem is the version of dash resumable upload. The most recent version is 0.0.4. You can only upgrade to 0.0.4 through installing it via the most recent github repository: https://github.com/westonkjones/dash-resumable-upload

If you want install if via command line (windows):

pip install git+https://github.com/westonkjones/dash-resumable-upload#egg=dash-resumable-upload
