76I finally have something resembling a semi-working "Shoutouts" app. It's disconcerting to me how "broken" it all is right out-of-the-box; it's not at all obvious that it has to be connected to an external data source (e.g. Sharepoint, Excel) in order for the values to stick when submitted, and then when you do that, other things break.
Using this video I finally got it working to the point where I can now post a shoutout, it saves the text values to a SharePoint custom list, and I can load the app and see it pull in those values in from SharePoint. The part I'm having trouble with is when a user posts a shoutout that includes an image attachment. It doesn't work as-is, and from what I read I can't "patch" a file to a SharePoint list the way I am the text values. I've looked at a bunch of guides that talk about "pulling images from SharePoint into a gallery" and some users have mentioned doing some kind of conversion to/from a "Multiple Lines" and an "Attachments" field, but I haven't actually found anything that goes into good detail on how to do this, using the context needed for it all to make sense with the Shoutout app.
Currently what I've got (based on the video mentioned earlier) is a "Multiple Lines" field in SharePoint called "Image," and when I submit a shoutout with a photo attachment this is the kind of thing I see in that field:
appres://blobmanager/2a3a41b5b4f0d844523423908724579d755/2
I don't know what this is, what to do with this, or how I can convert this into something usable. Clicking on the "Show photo" button in the app does nothing.
Does anyone else have a Shoutouts app connected to a SharePoint list that actually, fully works who could share step-by-step how they got around this issue?
