Azure Blob Storage - can list blobs but not delete blobs

Question

I am trying to delete a blob from our Azure container. I am able to connect to it and list all the blobs following the code in this question: Upload and Delete Azure Storage Blob using azure-storage-blob or azure-storage


CONNECT_STR = "DefaultEndpointsProtocol=https;AccountName=XXX;AccountKey=XXXXXXXXXX;EndpointSuffix=core.windows.net"
CONTAINER_NAME = "containername/"
blob_name = "productionmap/oursoftware/intended_blob_to_use.csv"

container_client = ContainerClient.from_connection_string(conn_str=CONNECT_STR, container_name=CONTAINER_NAME)

# Delete blob
container_client.delete_blob(blob=blob_name)

I am able to list all the blobs. I have tried to use a for loop to loop through the blobs and getting the specific blob to delete:

for x in bloblist:
  if x.name == 'intended_blob_to_use.csv':
    print(x.name)
    container_client.delete_blob(blob=x)

Above code is able to get the specific blobs name through the print but cannot delete it. Therefore it shouldn't have to do with the name of my file. The error message I receive is:

How come I cannot delete it? I am passing a key through the connection string and that user has "Owner" set on the storage.

Please try by changing `CONTAINER_NAME = "containername/"` to `CONTAINER_NAME = "containername"` (essentially remove the trailing slash in the container name). — Gaurav Mantri, Apr 11 '22 at 11:35

After reproducing from our end with the same code, we received the same error.

enter image description here

Like @Gaurav Mantri mentioned it is the extra trailing slash that caused the error which makes it point in a different path and causes BlobNotFound.
