Don't .read() the file that is given to Document(). Just give it the filename or you can give it an open file that has it's cursor set on offset 0. If the "file" you have is already a bytes object then you can use an io.BytesIO "in-memory" file to give to Document().

The docx_file parameter in Document(docx_file) can be a str file path or can be a file-like object (an open file created with open(...) or an in-memory file created with io.BytesIO), but it cannot be a bytes object (what is returned by file.read()).
