Path misleading display

[PikachuEXE]

I wrote a unit test for error message testing path & error message
My original unit test assert looks like

        assert_eq!(
            invalid_record.validate().unwrap_err().into_inner()[0],
            (
                Path::new("content_fingerprints").join("0"),
                Error::new("value is not a trimmed string"),
            ),
        );

And I got error

But actually the assert should be like

        assert_eq!(
            invalid_record.validate().unwrap_err().into_inner()[0],
            (
                Path::new("content_fingerprints").join(0),
                Error::new("value is not a trimmed string"),
            ),
        );
