Orchestration not triggering (stuck in Pending state)

[dawsonc2]

Hello! I am trying to create a durable function flow that basically creates a timer that triggers an orchestrator. According to the logs when i run "func start". Both triggers are generated appropriately and the first (the scheduler) executes successfully and creates an entry in the instances table for the orchestration with status of "Pending". However, this task never gets picked up and executed by the worker. Am I doing something wrong or is this a bug with the framework?

import azure.durable_functions as df
import azure.functions as func

from common.logging import get_logger

app = df.DFApp()

logger = get_logger(__name__)

scheduler_bp = df.Blueprint()
orchestrator_bp = df.Blueprint()

@scheduler_bp.function_name(name="scheduler")
@scheduler_bp.schedule(schedule="0 * * * 1 *", arg_name="timer", run_on_startup=True)
@scheduler_bp.durable_client_input(connection_name="AzureWebJobsStorage", client_name="client", task_hub="discovery")
async def scheduler(timer: func.TimerRequest, client: df.DurableOrchestrationClient):
    instance_id = await client.start_new("orchestrator")
    logger.info(f"Started orchestration with ID = {instance_id}")

@orchestrator_bp.orchestration_trigger(context_name="context", orchestration="orchestrator")
def orchestrator(context: df.DurableOrchestrationContext):
    logger.info("Starting Orchestrator")

app.register_blueprint(orchestrator_bp)
app.register_blueprint(scheduler_bp)

As a note I am running on MAC arm64. These are the logs of my run

Found Python version 3.12.10 (python3).
