Static file server gives error on URL with query at website root

[FunctionPoint]

Start with a fresh Pharo 13 image.
In a Playground window evaluate:

(ZnServer startDefaultOn: 3000)
    delegate: ( ZnStaticFileServerDelegate new
    directory: 'web' asFileReference;
    yourself).

Where the "web" subfolder contains some basic "index.html" file.

In a browser, browse to: "localhost:3000" and the website is shown correctly.

Now browse to "localhost:3000/?test" and the following error is shown:
"PrimitiveFailed: primitive #basicNew: in Array class failed"
.
Expected behavior:
The website is shown correctly
and the "?test" argument can be retrieved with JavaScript: Windows.location.search.

Checking further:
The error only occurs when the query is at the root level.
For example "localhost:3000/index.html?test" does not give an error and shows the website.
That will be the workaround.. :)
