The listener for function was unable to start. Why?

I just witnessed this. This link indicates Local Storage Emulator may not be running. I stopped debugging. Went to the Cloud Explorer and opened the local nodes to see blob content. This must have started the Local storage emulator. When I hit run again, Azure Functions Tools started up.

For anyone that is encountering this issue the following may help...

Azure Durable Functions rely on TableStorage, and the latest version of Azurite (v3) currently doesn't support TableStorage. As such, pull the Azurite repo and switch to the legacy-master (v2) branch and then run npm run start.
