Plotly Uncaught TypeError: Cannot read property 'key' of undefined at HTMLCanvasElement

I have generated a scatter matrix using px.scatter_matrix()

import plotly.express as px
df = px.data.iris()
fig = px.scatter_matrix(df,
    dimensions=["sepal_width", "sepal_length", "petal_width", "petal_length"],
    color="species")
fig.show()

fig.write_html("/.../scattermatrix.html",
include_plotlyjs="cdn")

I then:

  1. Open the file scattermatrix.html with Chrome
  2. Save the file to create scattermatrixV2.html
  3. Open the new saved scattermatrixV2.html

The new saved flashes into view and hten dissapers: V1 vs V2 Plot now working

I can see the following error: ERROR OF scattermatrixV2.html

I only have this issue with Plotly plots: scatter matrix and go.Figure(data= go.Parcoords.., while with the other plots i generate (px.parallel_categories, go.Figure() & fig.add_trace(go.Scatter... ) it works fine.

It seems to be simlar to Uncaught TypeError: Cannot read property 'keys' of undefined however i am not sure where to apply: "Use Object.keys(uniqVisitorDeviceType) instead."

Here is the scatter matrix V1 original file:
