Hi Folks,
Here are the details:
I prepared several .vf.json files (tested in Visual Studio Code → they are valid JSON, UTF-8, correct structure, small file size ~14 KB).
File extension is correct (.vf.json), confirmed via Finder on macOS.
When I try to import, the “Open” button remains greyed out, or I receive the error: “Unable to upload. Try again. Only one file can be imported at a time.”
I tested with:
Firefox (latest version, macOS)
Google Chrome (latest version, incl. incognito mode)
A completely new workspace
Drag & Drop and the “Browse” button
The result is always the same: the file cannot be selected or uploaded.
I’ve attached several screenshots to illustrate the problem:
Screenshot of the Import dialog showing the error message.
Finder information panel confirming the file type .vf.json.
Attempt in Chrome with the import window open.
Could you please check if there is currently an issue with the import feature, or if there are any specific requirements for .vf.json files that might have changed?
Thank you very much in advance for your support – I really need to get this project imported.
Best regards,
Jürgen Hoffmann
