How to trigger an event-triggered function in azure when a blob is create

Question

I created an event-triggered function in Azure (name of the function app: "stamevents", name of the function: "EventGridTrigger1". this is my function.json file:

{
  "scriptFile": "__init__.py",
  "bindings": [
    {
      "type": "eventGridTrigger",
      "name": "event",
      "direction": "in"
    }
  ]
}

and this is my init.py file:

import json
import logging

import azure.functions as func


def main(event: func.EventGridEvent):
    result = json.dumps({
        'id': event.id,
        'data': event.get_json(),
        'topic': event.topic,
        'subject': event.subject,
        'event_type': event.event_type,
    })

    logging.info('Python EventGrid trigger processed an event: %s', result)

Now, I want to trigger this function when I'm uploading a blob. So I went to my storage account, pressed on "Events" and chose "Azure Function". and create.

Next I chose the function app and the function I just created

But this is what I see and I don't understand what to do next, and how to make this function fire after I upload a blob.

Any help will be appreciated!

@Gandhi, I'm not looking for a blob trigger but for an event trigger. — Binyamin Even

I have reproduced in my environment and i got expected results. I followed this workaround: You can use Microsoft.Storage.BlobCreated as below in using azure functions:

Click on Azure functions in end point type then click on end point as below:

Upload a blob like below:

After uploading blob check the logs of event grid function app as below, you will get to know it has executed and event grid got triggered as below:

enter image description here

You can use Logics apps for triggering an event when a blob is created as below:

enter image description here

And when i upload a blob like below it runs and gets triggered as below:

enter image description here

Now when you check the run history it trigered as below:

And you can check as below:

So, in last you can check the events i created as below:

Hey, Thank you, super helpful! How do I connect only a specific storage account or even a specific container to the blobCreated event?
