Sudden initialWidth error

[X-lem]

Been using the beta for a few months now. Have not changed any of my code. Suddenly I'm getting the following error. Am I missing a variable I'm supposed to be setting? Looked through the docs but not seeing what I missed.

TypeError: Cannot read properties of undefined (reading 'initialWidth')

  28 | return _extends({}, options, {
> 29 |   initialWidth: (_options$initialWidth = options.initialWidth) != null ? _options$initialWidth : 300,
     | ^  30 |   initialHeight: (_options$initialHeigh = options.initialHeight) != null ? _options$initialHeigh : 200,
  31 |   getSeriesOrder: (_options$getSeriesOrd = options.getSeriesOrder) != null ? _options$getSeriesOrd : function (series) {
  32 |     return series;
