Azure Logic App - Overwrite Blob

Question

When using "Create Blob" to write a blob from Logic App to Blob storage v2, I get the following error when there's an existing file in that location.

{  
  "status": 409,  
  "message": "Another active upload session exists, please retry after some time.\r\nclientRequestId: 4778f0b6-25b8-4321-a1f7-d7a7a7925461",  
  "error": {  
    "message": "Another active upload session exists, please retry after some time."  
  },  
  "source": "azureblob-wus.azconn-wus-01.p.azurewebsites.net"  
}  

When looking at blob properties, the file has a Lock on the Lease. How can I a) clear the Lock so the operation completes, or b) force an overwrite?

Answer 1

@Noah Van Loen & @Ravi Palihena @Steven Tchir Operations you mentioned "delete/create" with the lease control can be achieved via Blob Service REST API and HTTP action. Before deleting blob, the lease should be established via lease container. The request header should contain headers: 'x-ms-lease-action: acquire' and 'x-ms-lease-duration: <value in seconds>'. The service will respond with a response code and unique lease ID 'x-ms-lease-id'. While the lease is active, You must include the lease ID with any request to delete the container or to renew, change, or release the lease.

Delete blob could contain a large number of snapshots and the operation could time out. If that happens, the client should retry the request, please refer to https://learn.microsoft.com/en-us/rest/api/storageservices/delete-blob#remarks

For releasing the established lease, request header should contain: 'x-ms-lease-id: <lease id>' and 'x-ms-lease-action: release'.

Archiving blob, for now, could be achieved in the following way: create a new blob container with the new name and copy blobs from the old blob container to the new one. Once the blobs are copied, you can delete the old blob container.

I ran into a similar issue and was able to address it by updating the parent for each component.
