Suggester not working as intended

[misakabestgirl]

I'm trying to make a suggester input prompt so I tried starting with the example shown in the documentation, but even that doesn't seem to work.

const pickedFile = await params.quickAddApi.suggester( (file) => file.basename, params.app.vault.getMarkdownFiles() );

The suggester appears correctly and it allows me to choose a note, but the output result is simply "[object Object]", regardless of what note I choose.

Is there anything I'm doing wrong?
