Series option stroke_dash is unknown

[passuff]

I would like to use dashed lines and added "stroke_dash" as a series option. Unfortunately I receive the following error message:

/// apexcharts-card version 2.0.4 /// value.series[5] is not a ChartCardSeriesExternalConfig value.series[5].stroke_dash is extraneous value.series[5].stroke_dash is extraneous

My Code is as following:

  colorize_states: false
