           I am trying to use embeddings and received the error `InvalidRequestError: Too many inputs. The max number of inputs is 1.  We hope to increase the number of inputs per request soon.` How do I fix this?

-          This error typically occurs when you try to send a batch of text to embed in a single API request as an array. Currently Azure OpenAI does not support batching with embedding requests. Embeddings API calls should consist of a single string input per request.

-> We currently do not support batching of embeddings into a single API call. If you receive the error `InvalidRequestError: Too many inputs. The max number of inputs is 1.  We hope to increase the number of inputs per request soon.`, this typically occurs when an array of embeddings is attempted to be passed as a batch rather than a single string.
