Cognitive-Speech-TTS | Microsoft Text-to-Speech API sample code | Speech library

I am trying to create an MP3 file using Azure Text to Speech. The node file runs, but nothing gets created or outputted. The Node.js docs files and example aren't too good

https://github.com/Azure-Samples/Cognitive-Speech-TTS

https://docs.microsoft.com/en-us/azure/cognitive-services/speech-service/get-started-text-to-speech?tabs=require%2Cwindowsinstall&pivots=programming-language-javascript

I need some guidance. My Azure function (written in node.js) will convert some random text to speech and then upload the speech output to a Blob. I will like to do so without using an intermediate local file. BlockBLobClient.upload method requires a Blob, string, ArrayBuffer, ArrayBufferView or a function which returns a new Readable stream, and also the content length. I am not able to get these from the RequestPromise object returned by call to TTS (As of now I am using request-promise to call TTS). Any suggestions will be really appreciated.

Thank you

Adding a code sample that can be tested as "node TTSSample.js" Sample code is based on

1. Azure Blob stream related code shared at https://github.com/Azure-Samples/azure-sdk-for-js-storage-blob-stream-nodejs/blob/master/v12/routes/index.js

2. Azure Text to speech sample code at https://github.com/Azure-Samples/Cognitive-Speech-TTS/tree/master/Samples-Http/NodeJS

3. Replace appropriate keys and parameters in the enclosed settings.js

4. I am using node.js runtime v12.18.3

5. Input text and the output blob name are hard coded in this code sample.
