Hi,
I'm fairly new to Instant Apps and not used 'Attachment Viewer' before and after some help to display attachments as i keep getting the error below.

I have activated enabled 'Attachments' as shown below, which i thought was the initial issue with displaying?

In the Map Viewer i have managed to create a Pop up which enables the image to display, using the URL in my attribute 'Go_Pro_Imm'.
As this seem to be drawing the image in successfully, i had assumed this is the image that would display in the attachment viewer window?

Many thanks,
Steve
