When I try to attach a PowerShell (.ps1) file to a memo and click Save, the action fails with an empty error message in the UI. The browser console shows:

StoreError: /memos.api.v1.AttachmentService/CreateAttachment INVALID_ARGUMENT: type is required

1. Open a new memo.
2. Add a .ps1 file.
3. Click Save.
4. Observe the error in the UI and browser logs.

The file should attach successfully.
