Attachments Are Not Opening in App

[AkshayManke]

Hi,

I have an App in which i have created one screen on which i have added View Form. While i am trying to click on any attachment i get the below message in a new tab and the attachments not opens.

<?xml version="1.0" encoding="ISO-8859-1"?>
<Error>
<Code>BlobNotFound</Code>
<Message>The specified blob does not exist. RequestId:901e-002a-5d99-fb4d2c000000 Time:2021-02-05T08:36:29.6925404Z</Message>
</Error>

Can anyone please help that how to rectify this issue?

Thanks,

@PeterTadrous Thanks for the demo video.

What I am trying to do is outside and without a Form.

I would like to add an attachment control into a gallery and then use the 'file' field from the table to show the in the control. Basically a list with each row has a file attachment control to download it.

BTW- I replicated your demo structure but I still could not see "filename" or "value" under the advanced tab of the attachment control.

I am using "File" type column and need that for download.

here are some screen shots:

No download:

No option to add filename or value:

And here's one how I am envisioning for my users to download files but the there is still not "Filename" or "Value" field:

If it helps to diagnose, I am on version 3.24031.26 of web-based PA.

thank you 🙂

Hi @ManishM

Thank you for the second video. You are very kind 🙂

My scenario is different from your demo scenario. I use Dataverse and use "File" type column. There is only 1 file allowed to be uploaded to it. This is the same file I would like my users to download. What you are showing seems possible in SharePoint. However, Dataverse stores file uploaded to "File" column in Azure Blob. That could be the case when I cannot see the 2 fields (Name and Value) when selecting the attachment control.

If you could be kind enough to make similar video with my scenario using Dataverse and File" type column, that would clarify a lot of things for me and for users facing this problem.

Thank you so much.

I have the same exact issue as @ManishM and can only make it work with the Form control. I don't understand what's the difference. I added the exact same formula for the Items property which is basically a Table with the record of the file.

When I copy the attachment control out of the form control,I face the same problem.And I can not see the filename and value property in the attachment's advanced property panel.I use it to customize the sharepoint list form.

Found the reason (kinda temp solution) for the 2 properties not showing. Turn off Power FX Formula Bar. There is a bug which removes the 2 properties - Filename and Value from attachment control. what I do is turn it off, work on the attachment control and then I turn it on. The attachment control holds the changes.

I've tested all the solutions mentioned here, but I'm still encountering the error. I'm attempting to save a blob file in the attachment data card. This functionality worked in the previous app, but it's not functioning in the new app. Is there a new update for this issue?

I've resolved the issue by following steps.

1. Turn on "Legacy formula bar"

2. This will activate the Name and Value section under Data Card Advanced settings.
3. Change the Value to AbosoluteUri.
