TypeError: object bool can't be used in 'await' expression

[yjoer]

Description

I am using JupyterLab v4.2.5 and v2.0.0 of the extension. It turns out that is_hidden(...) returned a boolean instead of an awaitable object. I found that Jupyter Server instantiated a synchronous contents manager instead of an async alternative. I removed the await keyword in L42 and the opener starts working correctly. A safer solution might be using ensure_async(...) as in the upstream handlers.

Reproduce

1. Activate the quick open dialog.
2. Type anything.
3. Find the error message in the terminal.

Expected behavior

It should return a list of files without errors.

Context

• Python package version: 3.11.9
• Extension version: v2.0.0
• Operating System and its version: Ubuntu 22.04.5 LTS
• Browser and its version: Chrome 129

Thanks @yjoer for the report.

Would you like to open a draft PR to try fixing this? Thanks!

I created a draft PR in #62 with a more precise finding.
