Hi All,
I am trying to add an image into a customer notification but I'm getting an error of "No usable issue is stored in context, unable to resolve filename"
In the screenshot, I have just used one of Google's doodle logos to test but this is not working.

I am not looking to make use of the customisable template for this as it is already in use.
Any advice on how to get the image to present would be greatly appreciated. Thank You!
