Accessing Custom Metadata in a Blob via Azure Logic App Trigger from Event Webhook

Question

How can custom metadata associated with a BLOB be accessed in an Azure Logic App triggered by an Event webhook?

I am trying to pass BLOB metadata to a Logic App, which will then send it via email when a BLOB is added to storage.

The metadata is defined on the Blob object as key-value pairs. An Event Subscription is triggered by a Blob Create event that sends a webhook to the Logic App. It appears that custom metadata is not included in the event schema and therefore not present in the payload.

The plan was to use the Get Blob Metadata (V2) action to retrieve the values and forward them to the next step, as this seemed like a logical choice. However, it does not work, even with the storage account and Blob values hardcoded in the Logic App. While it runs without errors, no metadata is accessible.

Is this possible?
