Theme settings don't work for bar charts and pie charts

[ddaaac]

Describe the bug
Theme settings don't work for bar charts and pie charts.
The chart is not rendered on the screen and an error like the screenshot below appears in the console window.
If I remove setTheme(~~), it works fine.

Steps or code example to Reproduce

ApexCharts().apply {
        setChart(Chart().apply { type = chartType })
        setLabels(*labels.toTypedArray())
        setTheme(Theme().apply {
            palette = "palette1"
            mode = Mode.light
            monochrome = Monochrome().apply { enabled = false }
        })
        ...

Expected behavior
I want to fill a palette color on my chart like below.

Screenshots

Maybe it is related to Monochrome#enabled.
