Hello, I am exploring a rebuild of one of our public facing apps using one of the newer Instant App templates, to meet a requirement for Google Analytics reporting. I've tried finding an existing post for this issue but no luck.
An important piece in rebuilding the app is displaying multiple images per feature within the pop-up, using dynamic URLs that use a {field_name} or ID to populate the URL.
It appears I am unable to do this using the New Map Viewer/JS 4.x apps, and instead receive a broken image.
Example URL: "https://sample.s3.amazonaws.com/Base_{field_name}.jpg"
When I click on the image to go to it directly in the browser, I can see the {field_name} is not populating in the URL.
An image using a static URL such as "https://www.sandiego.gov/sites/default/files/cosd-logo-initials-full-color-300ppi.jpg" works as expected:
I do believe this is intended to be a supported feature, as it is mentioned in the documentation and the option is there to include an select a field name:
What am I missing... or is this a bug?
Thank you!
