Azure blob storage trigger doesn't work

Question

I'm trying to create a event trigger for a pipeline. The trigger should be whenever the files in the below folder are created, and they are updated mostly everyday.

all the files in the folder have the same name except the endings are like 0-1, 0-10, 0-11, etc as shown below. I was set it up as choosing the 0-1.parquet file as the trigger.

The trigger of the pipeline I created is shown below, but it's not working. Can you please help me see if I set it up wrong? Thank you!

We have tried to test the blob events triggers on of my test storage account.

Created a test storage account and container name "pranathi" created directory "testdir" and uploaded blobs with 0-1.parquet

Now create Data Factory pipeline as below with blob path name ends with 0-1.parquet filter

Please provide the container name as /containername/ as shown in the below screenshot

In the data preview section i could see the 2 blobs are matching

Make sure to "Publish" for trigger to be activated after clicking "OK"

Now uploaded a new file Siva0-1.paraquet at 3:43pm IST

From the pipeline run could see a new event at the same time 3:43pm IST.

When you click on trigger runs you can see it ran for same trigger file name Siva0-1.parquet

Navigate to the Storage account -->Events -->select event subscription and see whether is it showing any matching events or any Delivery failed events

Also make sure the all the event type and Subjected filters are showing same which you have configured in pipeline and also please ensure you have all the Advanced filters as shown in the below screenshot.

Reference Article :https://learn.microsoft.com/en-us/azure/storage/blobs/storage-blob-event-overview#practices-for-consuming-events

If you want to ensure that the Microsoft.Storage.BlobCreated event is triggered only when a Block Blob is completely committed, filter the event for the CopyBlob, PutBlob, PutBlockList or FlushWithClose REST API calls. These API calls trigger the Microsoft.Storage.BlobCreated event only after data is fully committed to a Block Blob. To learn how to create a filter, see Filter events for Event Grid.

I have tried this, and it worked so please let us know if it worked for you.

Kindly let us know if the above helps or you need further assistance on this issue.
