end

@antarr @alexrudall I was able to fix this by avoiding the .embeddings method altogether and just doing

OpenAI::Client.json_post( path: "embeddings", parameters: { ... }, )

vs .embeddings which does the same but with "/embeddings". Looks like there's something weird about that / character Azure isn't liking
