Describe the bug
Since updating to the verison 2.1.0 line and area chart doesn't work in my dashboard. Column type works as before.

Version of the card
Version: 2.1.2

To Reproduce
This is the configuration I used:
Configuration that doesn't work:

type: custom:apexcharts-card
span:
  start: day
series:
  - entity: sensor.current_spot_electricity_price
    type: line
    color: lightblue
    show:
      legend_value: false
    data_generator: |
      return Object.entries(entity.attributes).map(([date, value], index) => {
        return [new Date(date).getTime(), (value) ];
      });

Configuration that works:

type: custom:apexcharts-card
span:
  start: day
series:
  - entity: sensor.current_spot_electricity_price
    type: column
    color: lightblue
    show:
      legend_value: false
    data_generator: |
      return Object.entries(entity.attributes).map(([date, value], index) => {
        return [new Date(date).getTime(), (value) ];
      });

Screenshots

Additional context
Everything was correct in version 2.0.4.
It appears in both instances of Home assistant I have.

I can confirm this bug, last functioning version is 2.0.4. (over one year old).
I found some apexcharts-card: TypeError: this.series is null and Uncaught (in promise) TypeError: this.w.globals.dom.Paper is undefined in the console log.
One theory could be that HomeAssistant has changed the availability of sensor-data (on load) and 2.1.x versions of apexcharts-card don't handle these situations. Apexcharts-card probably needs some mechanism to retry reading sensor-data without throwing an exception.
