Sharepoint images not displaying on mobile and workarounds give delegation error

(0) ShareShare
ReportReport
Posted on by 27

I have a responsive Canvas App which is built on dataverse which has a linked document library to sharepoint. I have a 'media' table where I'm storing additional information against the image. Users take the image in the canvas app, fill in the additional information and then the images are uploaded using a flow which creates the record and then attaches the url to the record in dataverse so that I can display it in a gallery in the canvas app.

 

The picture used in the canvas app gallery is just ThisItem.'Sharepoint Link' which displays the image without issue in browser, however in the mobile app none of the images render. I found this thread where the fix was to use a sharing link, I tried to do this using the 'Organisation' scope but this does not display images in either browser or mobile and I can't allow a sharing link that would give access to anyone due to sensitive images being uploaded. I also tried to use the Filter(StartsWith()) function that I've seen many people use however this is giving me a delegation issue and I will have a huge amount of records so I can't use this either.

 

Is there another solution for this?

    Hi @kves ,

     

    You can save ItemId from Create file action output into Dataverse table, then in the Gallery Image control use a LookUp function to get the image, display the thumbnail:

    LookUp(Library, ID = ThisItem.ItemId).Thumbnail.Small

     

    Best regards,

    Hi @v-jefferni,

     

    I have tried that and I get the delegation warning on this as well.

    Hi @kves ,

     

    This approach needs the column where stores the ItemId of type Number.

    Hi @v-jefferni,

     

    I've tried this and it seems to work intermittently, for some images it works and pulls back a thumbnail and for others it doesn't work at all. Using this also still doesn't display any images in the mobile device.

     

    I was uploading some images incorrectly to Sharepoint & that's why it was intermittent, I've fixed that now and your fix works for me, thank you!
