Attach a local file in computerUse when GTK Open does nothing

On the Bot computer, the native Open Files dialog can stay open after you click Open. The file is fine; the click never lands on the button. Staff on GTK file chooser Open no-ops describe a dock geometry bug: Open and Cancel sit on the bottom dock, so the click hits the dock instead of the dialog.

Confirm the geometry

When Open fails:

1. Look at the Bot desktop screenshot at the click moment.
2. Check whether Open sits on top of the dock icons at the bottom edge.
3. Note that drag-and-drop from a file manager can fail for the same overlap.

The same file may upload later if the dialog happened to open higher on screen.

Bypass the dialog (preferred)

Ask the Bot to set the page file input with DevTools and skip the chooser:

Use your browser tool to set the page’s file input directly with the DevTools command DOM.setFileInputFiles, pointing at /home/box/Downloads/your-file.mp4. Do not use the Open Files dialog.

Put the real absolute path on the Bot computer in that sentence. This path fully bypasses GTK Open.

If the site still forces the dialog

1. Ask the Bot to drag the dialog up by its title bar, or double-click the title bar to maximize, so Open sits above the dock.
2. Then click Open.

When you need staff follow-up

Send:

1. A screenshot of the Bot screen at the Open click (dock vs button).
2. The Request ID from that conversation (right-click the Bot message → Copy request ID).

Chat screenshot attach and “use Grok Bot on a site without a connector” are different flows.

Pitfalls

• Resetting the Agent Computer will not move the dock or fix dialog geometry.
• A successful upload on a later try does not mean the file was broken the first time — dialog position mattered.
