Date Only Config causing error selector

[azissofyanp]

this._context._display.widget.getElementsByClassName(...)[0] is undefined

That was after i tried to implement the

display: {
viewMode: 'clock',
components: {
decades: true,
year: true,
month: true,
date: true,
hours: false,
minutes: false,
seconds: false,
}
}

If not wrong, this is related to #2509 , for your case the fastest solution is to use viewMode calendar instead of clock as you're not using the clock component
