Using Plotly download option in Oracle BI EE

I was trying to implement a 3d mesh graph using plotly.js in a dashboard on Oracle BI EE version While trying to download PNG image of the chart I am getting the following error:-

Refused to load the image “…” because it violates the following Content Security Policy directive: "img-src ‘self’ data:*

Can’t put the full URL in the above error due to security reasons. Any idea how to fix this without changing the Oracle BI EE configurations? It works fine in an HTML file on my local machine.
