Hello, @Rain-H! I'm here to assist you with any bugs, questions, or contributions you might have. Let's work together to resolve the issue you're experiencing.

I found two similar discussions that might be relevant to your issue:

1. TypeError: argument should be a bytes-like object or ASCII string, not 'list' - This discussion is still open and might provide insights into similar error messages related to file uploads ^[1].

2. 知识库上传文件报错 - This discussion is also open and involves errors encountered during file uploads, although it is in Chinese ^[2].

For handling PDF files with mixed content types (text and images), Dify uses a combination of nodes to process different file types. You might want to ensure that the List Operation node is correctly configured to handle both document and image files, directing them to the appropriate processing nodes ^[3].

If the error persists, it could be related to the Document Extractor node's inability to process certain PDF features. Make sure that the PDF file adheres to the supported formats and size limitations, such as a maximum file size of 15MB and a limit of 10 files uploaded simultaneously ^[4].

To continue talking to Dosu, mention @dosu.
