Value cannot be null. (Parameter 'provider'). Failed to run Azure Functions. Please checkout console output

I am trying to run the example given [here](https://docs.microsoft.com/en-us/azure/developer/java/spring-framework/getting-started-with-spring-cloud-function-in-azure). I have installed the per-requisites.
JDK-1.8
maven-3.6.3
Azure-function-core-tools - 2.7.2628 (Installed by giving command - npm install -g azure-functions-core-tools@3 )
When I run `mvn azure-functions:run` I get below error.

I have gone through the similar issues created earlier. But nothing applies to the issue I am facing. I have done no changes in the example provided and I am expecting it to run. What does it mean by provider value is null. Can somebody please guide me on what is missing here.

Full log with debug on is attached.
[azure-functions-run-full-debug-log.txt](https://github.com/Azure/azure-functions-core-tools/files/4977062/azure-functions-run-full-debug-log.txt)

Start with the hello-spring-function-azure example and reproduce the failure with `mvn azure-functions:run`. Read the attached full debug log alongside the Azure Functions Java worker startup output and the reported Core Tools version. Done means identifying the cause of the null provider error and documenting verified steps that let the example run successfully.
