DartError: TypeError: "https://cdnjs.cloudflare.com/ajax/libs/pdf.js/3.2.146/": type 'String' is not a subtype of type 'Never' #1761

In my project I used overriding feature for loading pdf.js from another cloud storage.

  <script>
    // PDF.js options
    var dartPdfJsBaseUrl = "https://cdnjs.cloudflare.com/ajax/libs/pdf.js/3.2.146/";
  </script>

So the result URL should be https://cdnjs.cloudflare.com/ajax/libs/pdf.js/3.2.146/pdf.min.js.

Now I get this error:
