Credential parameter not being accepted

[shrazvi]

I am testing the RAG (TSQL) sample provided here - https://github.com/Azure-Samples/azure-sql-db-chatbot

On step 5 (05-get-search-vector.sql), the script provided is not working. What value should I put in the "Credential" parameter?

begin try
exec @RetVal = sp_invoke_external_rest_endpoint
@url = '<OPENAI_URL>/openai/deployments/embeddings/embeddings?api-version=2023-03-15-preview',
@method = 'POST',
@credential = [https://<OPENAI_URL>.openai.azure.com],
@payload = @payload,
@response = @response output;
end try
