Hello

I have created an power app with a camera control and a library to see the photo and to save it to a SharePoint list as attachement.
It was working before but after a couple of weeks ago it starts not saving the photo as atachment in the list.

The code for the button to make a photo is:

UpdateContext({varPID: GUID()});
Collect(
    colImage2,
    {
        Value: Camera1.Stream,
        DisplayName: Text("Mikel-" &
            Now(),
            "[$-en]hhmmss"
        ) & ".jpg",
        Id: varPID,
        AbsoluteUri: ""
    }
)

So I can see the image in a library include displayname.
The library is using as Items: colImage2

In the EDIT form for the SharePoint list I have two fields: TITLE and ATTACHMENTS
The ATTACHMENT control is using for Items: colImage2

The save button has the following formula:

Patch(Brazil_Attachment_Picture, frmFoto.Updates); // The form name of the SharePoint list
Clear(colImage2);
Refresh(Brazil_Attachment_Picture);
ResetForm(frmFoto)

THE PROBLEM
I cannot save the attachment, which was possible before.

I don't know if thats a problem of a Microsoft update of the PowerApps environment.

Thanks in advance for helping out.

Kind regards
Michael

Building Power Apps

The issue you're facing could be related to changes or updates in the Power Apps environment, but let's first troubleshoot based on your current setup. Here are a few things you can check and update in your app:

1. Review the Camera Control

Ensure that the Camera1.Stream is still correctly capturing the image. A good test is to display the image on a label or gallery control to ensure the camera is capturing the stream properly.

2. Format for Attachments

In your formula for saving attachments to SharePoint, the image stream needs to be converted to a format SharePoint can recognize, like base64 encoding. However, SharePoint lists expect an actual file or image as an attachment, not just a stream.

Try modifying the Collect function to include base64 encoding:

Collect(
    colImage2,
    {
        Value: JSON(Camera1.Photo, JSONFormat.IncludeBinaryData),
        DisplayName: Text("Mikel-" & Now(), "[$-en]hhmmss") & ".jpg",
        Id: varPID,
        AbsoluteUri: ""
    }
)

3. Form's Attachment Control

Check that the Attachments control is still correctly bound to the form. Sometimes, it loses its connection to the data source, and you need to re-establish it.

Make sure that frmFoto is bound to the correct SharePoint list (in this case, Brazil_Attachment_Picture).
In the form, ensure that the Attachments control is set to colImage2 and is allowed to upload images.

4. Use Patch with Attachments

Instead of directly using Patch(Brazil_Attachment_Picture, frmFoto.Updates);, try using SubmitForm(frmFoto) to submit the form with the attachment. The Patch function may not handle file attachments in the same way as the SubmitForm function does.

Here’s an alternative approach for the Save button:

SubmitForm(frmFoto);
Clear(colImage2);
Refresh(Brazil_Attachment_Picture);
ResetForm(frmFoto);

5. Check for Updates or Known Issues

If everything worked previously and stopped after a couple of weeks, it's possible that an update might have affected the behavior of file attachments. You could try reverting to an earlier version of your Power App to see if that resolves the issue, or check Microsoft Power Apps updates for any reported issues.

6. Check File Size Limits

Sometimes, there could be issues if the file size exceeds certain limits imposed by SharePoint or Power Apps. Ensure that the images captured by the camera control are within a reasonable size.
