Creating Python HTTP template generates wrong value for --authlevel 'anonymous'

[yonahcitron]

Version

4.0.5907

Description

Problem

Create a new python function app, and add an http trigger template passing --authlevel anonymous or --authlevel ANONYMOUS.

This template generates the incorrect auth_level constant in the decorator: @app.route(route="MyHttpFunction", auth_level=func.AuthLevel.Anonymous)

It should be upper-case: @app.route(route="MyHttpFunction", auth_level=func.AuthLevel.ANONYMOUS)

When you run the buggy template, it will give you: [2024-07-30T13:23:33.803Z] Exception: AttributeError: Anonymous

NOTE

This bug only occurs when passing the parameters explicitly.

If you run it without the flag, i.e.: func new --template "HTTP trigger" --name MyHttpFunction

It will prompt you:

Select a number for Auth Level:
1. FUNCTION
2. ANONYMOUS
3. ADMIN

And the resulting generated template will have the correct constant value.

Steps to reproduce

Code to Execute

mkdir test_function && cd test_function

func init . --python

func new --template "HTTP trigger" --name MyHttpFunction --authlevel anonymous

func start

Tagging @shreyabatra4 to route the issue to the appropriate team.

Same here @4.0.6280, lost 2h today during a lesson with students.

FYI: official docs shows WRONG command https://learn.microsoft.com/en-us/azure/azure-functions/create-first-function-cli-python?tabs=linux%2Cbash%2Cazure-cli%2Cbrowser#create-a-local-function

[julicjung]

Same here, lost a couple of hours and figured out by comparing painfully and step by step. Please do also fix the docs.

[yonahcitron]

Created a tiny PR that should fix this, here.

Incidentally @aaglietti-itsrizzoli , the lower-case 'anonymous' arg given the documentation should work fine. The user's string isn't passed as a literal, it's first put into an enum
