Access to Image from origin 'null' has been blocked by CORS policy

Question

I have JavaScript application in OpenLayers 3, and my base layer is created from local tiles. I work only in my computer so I do not know why I have CORS error.

Answer 1

To solve your error I propose this solution: to work on Visual studio code editor and install live server extension in the editor, which allows you to connect to your local server, for me I put the picture in my workspace 127.0.0.1:5500/workspace/data/pict.png and it works!
