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 only supports arrays of embeddings with multiple inputs for the text-embedding-ada-002 Version 2 model. This model version supports an array consisting of up to 16 inputs per API request. The array can be up to 8191 tokens in length when using the text-embedding-ada-002 (Version 2) model.
