I found a book that I can't convert with this plugin.

Exception content:

Exception: rb element not a child of ruby element: b'<ruby><span><rb-bad>珠</rb-bad><img src="image_rsrcCED.jpg" alt="" style="-kfx-render: inline; -kfx-style-name: s5FU; box-sizing: content-box; height: 1em; max-height: 100%; vertical-align: baseline; width: 1em"/></span></ruby>'

I analyzed this problem by myself and concluded this check is not required (at least in my case).

This book uses the image for non-standard characters, so

<ruby><rb>珠</rb><rt>ruby1</rt><rb><img ... /></rb><rt>ruby2</rt></ruby>

is desired.
I slightly modified the code to the below and confirmed it works in my case:

                        while rb_elem.getparent() is not event_elem:
                            if len(rb_elem.getparent()) != 1:
                                # rb_elem.tag = "rb-bad"
                                # raise Exception("rb element not a child of ruby element: %s" % etree.tostring(event_elem))
                                break  # CHANGED to break

                            rb_elem = rb_elem.getparent()

                    rb_elem = self.replace_element_with_container(rb_elem, "rb")
                    rb_parent = rb_elem.getparent()  # ADD

                    ruby_id = ruby_id_entry.pop("$758")
                    ruby_content = self.get_ruby_content(ruby_name, ruby_id)

                    if ruby_content.pop("$159") == "$269":
                        rt_elem = etree.Element("rt")

                        rb_parent.insert(rb_parent.index(rb_elem) + 1, rt_elem)  # MODIFIED to rb_parent
