CORS Setup

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 has been tainted by cross-origin data.

If you are loading images from external sources (e.g. from an AWS bucket), you need to first configure Cross-Origin Resource Sharing for both the server and the image:

  • 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)
