HuggingFace Custom Embedder raises error when used with PDFUrlKnowledgeBase

[DarkDk123]

I was implementing a RAG with HuggingfaceCustomEmbedder and PDFUrlKnowledgeBase as follows:

It raises the following NotImplementedError while loading documents (maybe)

Maybe it's not implemented yet in HuggingFace Embedder

Huggingface Embedder calls the Base method, it raises Not implemented!
