Using Arcade to Display Clickable Attachment Links in Map Tips
I found an article with Arcade Expression Examples, including one for Clickable Attachment Links.
I copied and pasted the code to create an Arcade replacement token for a layer in one of my maps and replaced the URL with the same layer's URL. However, I can't get it to work. It always says "None", even for features that I know have attachments.
The two main differences between the layer in the sample site and the layer that I'm trying to implement this for are that my layer is a map service as opposed to a feature service, and it's secured.
Has anyone else successfully included attachment links in their map tips for a secure service using Arcade Expressions or any other method?
Thanks,
Denise

Hi Denise. I just tried this and getting same result as you.
As a test, I tried a simpler arcade expression like this:
return Count(Attachments($feature))
That should return a count of how many attachments for each feature, but nothing is returned.
FYI, tried this with a map service as well as feature service.
So, it seems the Attachments function is not working...

Thanks for your reply, Zorba. I tried something similar to your expression, but it didn't work for me either. I suspect it's because the service is secured. It's frustrating, but I did manage a workaround. The data for this particular service is stored in SQL, so I used a Data Link to the attachment table to get a count of attachments. Now the users will at least know when to look for attachments.

Good idea with using data links. That could come in handy for some of our apps as well. Thanks. 0 -
Did anyone get this to work? Same issue here. Unsecured service, tried both map service and feature service. returns 0 with Count(Attachments($feature)) but shows attachments below in the Attachments section so they are definitely there

Hi Chelsea,
Unfortunately, I have not gotten this to work. I looked at the URL of an attachment by using the link in the Attachments section. I believe we would need some way of getting the token to build it into the URL. As far as I can tell though, Arcade doesn't have the capabilities to grab the token.
