Error creating configuration card

Firstly, This is excellent. I have used 2 graphs previously to track short term and long term CPU usage and this provides exactly what I was trying to achieve. Thank you.

I had a problem this morning, I am seeing this error when I edit the card:-

Configuration errors detected:

*** document.createElement(...).constructor.getConfigElement is not a function**
The card config which was working last night is as follows -

type: custom:plotly-graph
entities:

• entity: sensor.load_1m
• entity: sensor.processor_use_percent
  hours_to_show: 2
  refresh_interval: 10
  title: CPU Load
  Clearing the browser cache had no effect but a restart of HA seemed to resolve it so it could be an issue with my setup.

I will convert more of my graphs to plotly and let you know if anything else occurs.
