   at Spotfire.Dxp.Application.Visuals.ValueRenderers.ImageFromUrlService.TryGetImageFromUrl(Uri url, Image& image)

 

Resolution:
This error generally indicates that there was an issue with authentication at the image source.  The Spotfire Web Player service will not pass any SSO credentials along to the source to get the images, so authentication requirements must be removed to make the images work in Spotfire Web Player. Ensure the images URL is generally accessible from the Web Player's Node Manager machine with no authentication step and the image will be properly displayed in Spotfire.
