Hello,
Referring to the article AI Ready Apps: From RAG to Chat – Interacting with SQL Database in Microsoft Fabric using GraphQL an... on the Microsoft Fabric Blog,

I tried to add an Azure Blob Storage event from Add Trigger in a Microsoft Fabric pipeline.

However, I get the following error and cannot complete the rule creation:

“Failed to create rule. Please check your network connection, refresh the page, and try again.”

Do you know how to resolve this?

Environment information

・Fabric capacity region: Japan West (Trial)

・Azure Blob Storage region: Japan West

・Azure subscription and resource group region: US East

・Account permissions: Contributor, EventGrid EventSubscription Contributor, and EventGrid Contributor at the subscription level; ・Storage Blob Data Owner and Contributor for the Blob Storage

・No specific network restrictions

Things I have tried

・Deleted existing event subscription from Blob and recreated it (I thought it might be due to duplication, but it didn’t help)

・Enabled “Share data externally” and “Receive data from external sources” in the Fabric tenant settings

After that, when I tried to open the eventstream created by the pipeline, I got the following error:
Failed to create or update event subscription, workspaceId：～
 

I can see that an event subscription has been created on the Azure blob side.
