Event Hub Checkpoint Data is Not Saved

I am running the event hub receiver implementation from: https://docs.microsoft.com/en-us/azure/event-hubs/event-hubs-python-get-started-send#create-a-python-script-to-receive-events and I haven't changed anything except the connection strings etc.

After creating hundreds of events, I can see that the receiver created checkpoint folder inside the storage account, but as I run the receiver again I see that it processes the same events.

The files that are created per partitions also are empty.

The storage is provided in the consumerClient:

checkpoint_store = BlobCheckpointStore.from_connection_string("...", "eventhubcontainer")      client = EventHubConsumerClient.from_connection_string("...", consumer_group="$Default", eventhub_name="eventhub1", checkpoint_store=checkpoint_store)  

Also after reading the event there is method saving the checkpoint:

await partition_context.update_checkpoint(event)  

Am I missing something here?

The whole code:

import asyncio  from azure.eventhub.aio import EventHubConsumerClient  from azure.eventhub.extensions.checkpointstoreblobaio import BlobCheckpointStore    async def on_event(partition_context, event):      print("Received the event: \"{}\" from the partition with ID: \"{}\"".format(event.body_as_str(encoding='UTF-8'), partition_context.partition_id))      await partition_context.update_checkpoint(event)    async def main():      checkpoint_store = BlobCheckpointStore.from_connection_string("AZURE STORAGE CONNECTION STRING", "BLOB CONTAINER NAME")      client = EventHubConsumerClient.from_connection_string("EVENT HUBS NAMESPACE CONNECTION STRING", consumer_group="$Default", eventhub_name="EVENT HUB NAME", checkpoint_store=checkpoint_store)      async with client:          await client.receive(on_event=on_event,  starting_position="-1")    if __name__ == '__main__':      loop = asyncio.get_event_loop()      loop.run_until_complete(main())
