Please find the traceback attached below.

Although this fixes the error that is raised and not caught, it sets the author name to "", which implies that it will ignore the author name from meta.

    def extract(self):
        authors_from_schema = self.__get_authors_from_schema()
        authors_from_meta = self.__get_authors_from_meta()
        if authors_from_schema:
            return authors_from_schema
        return authors_from_meta

Instead, you should perhaps use something like below:

    def __get_authors_from_schema(self):
        authors = list()
        if self.article.schema and "author" in self.article.schema:
            schema_authors = self.article.schema["author"]
            if isinstance(schema_authors, dict):
                schema_authors = [schema_authors]
            for author in schema_authors:
                if isinstance(author, dict):
                    author = author.get("name", None)
                    if author:
                        authors.append(author)
                else:
                    authors.append(author)
        return authors

I received this error on a page prepared by Reuters, where the author in the schema was an object "author":{"@type":"Person","byline":"Nia Williams"}, which has no name key.
