6 months ago I also have this issue after adding changing a type into a Union type.

🐛 Describe the bug When running durable function activity in 3.11, it throws the below error:
Exception: FunctionLoadError: cannot load the Hello1 function: binding payload has invalid non-type annotation list[str] Stack: File "C:\Program Files\Microsoft\Azure Functions Core Tools\workers\python\3.11/WINDOWS/X64\azure_functions_worker\dispatcher.py", line 393, in _handle__function_load_request self._functions.add_function( File "C:\Program Files\Microsoft\Azure Functions Core Tools\workers\python\3.11/WINDOWS/X64\azure_functions_worker\functions.py", line 338, in add_function input_types, output_types = self.validate_function_params(params, ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "C:\Program Files\Microsoft\Azure Functions Core Tools\workers\python\3.11/WINDOWS/X64\azure_functions_worker\functions.py", line 185, in validate_function_params raise FunctionLoadError(However, the same works fine in 3.10.
🤔 Expected behavior Should run without any errors/exception.
☕ Steps to reproduce Core Tools Version: 4.0.5455 Commit hash: N/A (64-bit) Function Runtime Version: 4.27.5.21554
Create a durable function activity in VS Code (v.13.1 - azure function extension) with the following code:
init.py `import asyncio import azure.functions as func
async def main( payload: list[str] , outputblob: func.Out[str] ) -> str: outputblob.set( payload[0] + payload[1] ) return("Finalout")`
function.json
{ "scriptFile": "__init__.py", "bindings": [ { "name": "payload", "type": "activityTrigger", "direction": "in" } ], "disabled": false }Then run in debug mode and you will find the above exception in terminal window.
