How to set to true?: 'This application requires a layer that supports attachments and has 'supportsQueryAttachments' set to true'

[Amarz]

Hello,

I am receiving this error when attempting to use the Attachment Viewer Instant App but can't find resources on how to set to true 'supportsQueryAttachments'.

This application requires a layer that supports attachments and has 'supportsQueryAttachments' set to true.

Enterprise 11.2 with ArcPro 3.2.

Data is inside an Enterprise GDB and published as a feature service to Portal.

Hello @Amarz, 

when you check your Feature Service, has this service Attachment enabled, and please check the QueryAttachment is present in the REST page of the layer in the Feature Service:

Hey Amarz,

I'm still on 11.1 but I'm having the same issue. I've found that if you have published a dataset where only some of the feature layers have attachments that it will throw this error. If you create a new map with only the layers with attachments you should be able to get it to work.
