Hello,
For your xod documents, it appears that your server isn't handling the range requests for the documents properly. Instead, it is returning the entire file. You could load the file by setting streaming: true, however we highly recommend handling range requests properly or you may run into performance & memory problems for larger documents.
For your pdf documents, it looks like the file path doesn't have an extension, so WebViewer assumes that it's a xod file. You will need to explicitly tell WebViewer that it's a pdf by passing the option documentType: "pdf" when instantiating.
