Failed to publish and activate the trigger

Aaron Hu 20

Hi,

I built a pipeline in Synapse and added an event trigger on it so the pipeline will be executed once a new file is uploaded to my storage account.

The issue is that I couldn't activate the trigger. When I started the trigger and clicked "Publish All", it showed an error message "Failed to activate file-added-etl (Trigger).

I am pretty sure all dependencies were published and I have registered all required services including EventGrid and DataFactory.

I once succeed published and activated a trigger by simply trying multiple times.

Can anybody help and explain why this happens?

A lot of thanks!

Aaron

Hi @Aaron Hu

Thank you for posting your query!

It seems that the trigger in your Synapse pipeline is not activating as expected. Here are some potential reasons and recommendations to assist you.

Permissions - Ensure that the Azure account you are using has the necessary permissions to create and activate triggers. You need to have the Owner or Contributor role on the storage account or the specific permission Microsoft.EventGrid/EventSubscriptions/Write to the storage account.

Event Grid Registration - Although you mentioned that you have registered all required services, double-check that Event Grid is properly set up and linked to your storage account. If there are any issues with the Event Grid configuration, it could prevent the trigger from activating.

Dependencies - Even if you believe all dependencies are published, it's worth verifying that there are no missing components or configurations in your pipeline that could affect the trigger's activation.

Retry Mechanism - As you noted, sometimes simply trying multiple times can lead to success. This could indicate that there might be intermittent issues with the service or network that resolve themselves upon retrying.

Monitoring and Logs - Check the monitoring logs for any additional error messages or details that could provide insight into why the trigger activation failed.

The problem is solved. I deleted all EventGrid related resources in my resource group and re-regeistered EventGrid and DataFactory services. I also deleted old trigger and created new one. After doing all this, the new trigger activated successfully.Well, I still don't know the reason why it failed to activate. Feel free to share any opinions if you have any clue.

Thanks for your reply anyway.
