Quick File Open fails to show any file that isn't listed as recent

[planger]

Bug Description:

Steps to Reproduce:

1. Hit Ctrl-p to open quick file open: Recent files show up
2. Start typing any character: the list vanishes and no file matches are shown even though there would be matching files

Expected result: all non-ignored files with the entered character are shown instead of an empty list

Notes:
If you hit Ctrl-p again to include hidden files, all seems to work fine.
So it may have to do with the file search service failing to provide results if hidden or ignored files shall be filtered.

I'm certain this is a regression with 1.58.0 and worked fine on master before the release.

Additional Information

• Operating System: Ubuntu 22.04
• Theia Version: 1.58.0

Possibly a regression from #14365.

Edit: Nevermind, it's unrelated. Possibly a regression from #14737?

@tsmaeder ?

I can't reproduce this on Windows.

@planger works fine for me on Ubuntu 22.04, as well (Electron). Also browser version on Windows.

Thanks for testing! I retested this now in more detail. It looks like for the workspace I am using I get the following error:

2025-02-04T09:34:20.323Z root ERROR Failed to search: file:///home/philip/Git/OpenSource/openai-prompt-flow-boilerplate Error: "/home/philip/Git/OpenSource/Theia/theia/examples/browser/lib/backend/native/rg" exited with code: 1

    at ChildProcess.emit (node:events:519:28)
    at ChildProcess._handle.onexit (node:internal/child_process:294:12)

For other workspaces, file search seems to work fine. Not sure what the issue with this workspace is.

@planger does Theia IDE work on the exact same workspace?

I cloned https://github.com/eclipsesource/openai-prompt-flow-boilerplate and still can't reproduce. @planger I guess you'll have to generate some data on your machine to get to the bottom of this.

Thank you again for investigating! It turns out that there is something broken in this specific workspace. I cleaned it and now it works again. Sorry for the confusion!
