Editing apps with Studio version 3.23032.5 (to avoid ParseJSON-related issues) I have found an error occurs in forms showing the attachment field of SharePoint list records. To reproduce the error:

Start a new Canvas app
Connect to a SharePoint list
Add a gallery for the list
Add a form whose source is the same list and which is linked to the gallery (Item: Gallery1.Selected)
Update the App > OnError property to display errors:
- Notify("An error has occurred: " & FirstError.Message, NotificationType.Error);
Select a list item with attachments: the attachments are shown in the Attachments field in the form
Select a list item with no attachments: an error message is displayed with no content
- An error has occurred:

I have several apps which were working fine but now generate errors in these same circumstances.
