Java Azure function in MacOS M1 does not work when running locally with Maven or IntelliJ and does not show logs but it does work with C#

I'm working with a MacOS M1 and I'm trying to create an Azure function using Java and Maven.

I've followed all the steps here: https://learn.microsoft.com/en-us/azure/azure-functions/functions-create-maven-intellij

And also here: https://learn.microsoft.com/en-us/azure/azure-functions/create-first-function-cli-java?tabs=macos%2Cbash%2Cazure-cli%2Cbrowser

That is to say, I've configured the JAVA_HOME environment to point to my JDK 11 version, etc. and tried to run the Azure function both in IntelliJ and with mvn azure-functions:run command.

In both cases I don't get any error but the only logs I can see are the following:

Extension bundle specified, skip install extension

It's very weird because it doesn't seem to be running the func start command or something like that. It's not detecting my Function which is correctly annotated with @FunctionName("HttpTriggerJava") and all other details that the Microsoft Azure documentation states.

On the other hand, if I follow the docs for creating an Azure Function with C# everything works as expected. Following is the link: https://learn.microsoft.com/en-us/azure/azure-functions/create-first-function-cli-csharp?tabs=macos%2Cazure-cli

Below are the logs I'm getting after running func start:

Finally, if I hit the endpoint http://localhost:7071/api/HttpExample I'm getting the expected response.

Did anyone experience this issue? I'm stuck with this, I've spent almost the whole day struggling with this and didn't find any solution. I wouldn't want to work with C#.

Thanks in advance

The issue could be due to the way the function core tools handling the Azure function.

As I have mentioned in the comments, change authLevel = AuthorizationLevel.Anonymous in function code to resolve the issue.

Code Snippet:

@FunctionName("HttpExample")
    public HttpResponseMessage run(
            @HttpTrigger(
                name = "req",
                methods = {HttpMethod.GET, HttpMethod.POST},
                authLevel = AuthorizationLevel.ANONYMOUS)
                HttpRequestMessage<Optional<String>> request,
            final ExecutionContext context) {
        context.getLogger().info("Java HTTP trigger processed a request.");

        // Parse query parameter
        final String query = request.getQueryParameters().get("name");
        final String name = request.getBody().orElse(query);

        if (name == null) {
            return request.createResponseBuilder(HttpStatus.BAD_REQUEST).body("Please pass a name on the query string or in the request body").build();
        } else {
            return request.createResponseBuilder(HttpStatus.OK).body("Hello, " + name).build();
        }
    }

Output:
