Issue Summary

On the confluence pages, uploading an attachment automatically inserts the view-file macro, which fails to render and shows an error instead of previewing the file.

Environment

• Confluence Cloud
• Legacy editor pages/ new editor pages 
• Affected macro: view-file

Steps to Reproduce

• Open or create a page that uses the legacy editor.
• Upload a file via “Files & images” or by drag-and-drop (try files that are not images - images seem to work as expected)
• Publish or preview the page.
• Observe the auto-inserted view-file macro where the attachment is placed.

Expected Results

• The uploaded file renders inline as a preview, or the attachment is displayed using a working viewer/thumbnail.

Actual Results

• The macro fails to render the uploaded attachment and displays:

   Error rendering macro 'view-file' : Cannot render content of attachment

Workaround

• Or replace the view-file macro with a working, file-type-specific macro (for example, viewxls for spreadsheets).

Notes

• Issue observed consistently on legacy editor pages or new editor immediately after uploading an attachment (a xlsx file, for example).
• The problem appears limited to the view-file macro; switching to another macro restores inline rendering.
