My Research

• this is the the line that crashes:

  apexcharts.js/src/modules/Range.js

  Line 174 in 841e5f0

  val.toString().split('.')[1].length

  because val is 0
• reason for this is because Utils.noExponents is rounding 1e-7 down to 0:

  apexcharts.js/src/utils/Utils.js

  Line 154 in 841e5f0

  return Math.round(num) // Round the number

• Looking at the commit history, it seems 97ed0dc is the cause. Downgrading to 4.2.0 fixes it
