Getting error 'HttpResponseError: () The given API key doesn't match' in textsplit-data-chunking-example.ipynb

Getting an 'HttpResponseError: () The given API key doesn't match service's internal, primary or secondary keys.' in error in search_index_client.create_or_update_index(index)

I have validated that my azure_openai_key is valid. I have tried it with API Key for my text-embedding-ada-002 embedding as well but it still gives me the same error.

Start with textsplit-data-chunking-example.ipynb and the call to search_index_client.create_or_update_index(index). Trace which Azure service endpoint and key the example uses, then compare that pairing with the key being supplied for Azure OpenAI or text-embedding-ada-002. Done means the index creation runs without the API-key mismatch error.
