CORS issues

The following error messages indicate that the image you have passed to the SDK could not be loaded due to Cross-Origin Resource Sharing (CORS):

• Failed to execute 'texImage2D' on 'WebGLRenderingContext': The cross-origin image at [...] may not be loaded.
• SECURITY_ERR: DOM Exception 18
• Unable to get image data from canvas because the canvas as been tainted by cross-origin data.

In this case:

• If you’re loading images from S3, make sure you created a CORS policy for your S3 bucket (More information here)
• If you’re loading images from your own server, make sure the CORS header is set (More information here)
• Make sure you enable CORS for the loaded image (More information here)
