Vector search index creation failed

MongoDB Atlas Atlas Search

when I try to create a vector search for my embeddings I get the following error message

Your index could not be built: Unexpected error: VectorValuesField “$type:knnVector/article_emebeddings” appears more than once in this document (only one value is allowed per field)

@kalyanakannan_padivasu, Can you please share what index definition you were using? Also, from where are you creating the index (I’m guessing Atlas UI, but it is good to confirm)
