We’ve started seeing the word “null” starting to show up from time to time in the middle of certain textual responses – e.g., inside a section heading. Ours is a RAG application built on top of the Assistants API. We’ve double-checked and can say that the word “null” never shows up anywhere in our RAG (vector store) content.
Has anyone else seen these kind of nulls?
Interestingly, we have also implemented the Responses API on top of the same vector store. We are not seeing anything similar via that API.
