[BUG] DatePickerSingle broken in Dash 1.3.0

[davidghill]

Describe your context
I'm running an app that allows the user to select options and kick off a process. The code for the control is below:

        html.Div([
            html.Label('Operating Date'),
            dcc.DatePickerSingle(
                id='operating-date-picker',
                min_date_allowed=datetime(2010, 1, 1),
                max_date_allowed=datetime(2099,12,31),
                initial_visible_month=datetime.today().date() - timedelta(days=1),
                date=datetime.today().date()- timedelta(days=1),
                day_size=47,
            ),
        ], style={'width'  : '10%',
                  'display': 'inline-block',
                  'marginLeft' :10, 
                  'marginRight':10, 
                  'marginBottom':10}),

Describe the bug

When you click on the date picker, the application crashes with the message listed under the screenshots section.

Expected behavior

Clicking on the datepicker control should bring up the ability to select a date.

Screenshots

@Marc-Andre-Rivet I can reproduce the problem, candidate for patch

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

app = dash.Dash(__name__)
app.layout = html.Div([
            html.Label('Operating Date'),
            dcc.DatePickerSingle(
                id='operating-date-picker',
                min_date_allowed=datetime(2010, 1, 1),
                max_date_allowed=datetime(2099,12,31),
                initial_visible_month=datetime.today().date() - timedelta(days=1),
                date=datetime.today().date()- timedelta(days=1),
                day_size=47,
            ),
        ], style={'width'  : '10%',
                  'display': 'inline-block',
                  'marginLeft' :10,
                  'marginRight':10,
                  'marginBottom':10})

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

Seems linked with the ramda update from 0.24 to 0.26 (Notes from 0.25 release: ramda/ramda#2319)

import R from 'ramda' must now be import * as R from 'ramda'

I can't explain right now why the builds have passed in CI atm.
Working on fixing this.

@Marc-Andre-Rivet I'm investigating the build history, might relates to the same issue as in dash

[davidghill]

Wow that was quick!

[Marc-Andre-Rivet]

@davidghill The regression fix has been released.
