Unable to get azblob.StorageError for block blob operations

Steps to reproduce

• Download the latest versions of github.com/Azure/azure-sdk-for-go
• Run simple block blob client and try to get properties for non-existing block blob:

import "github.com/Azure/azure-sdk-for-go/sdk/storage/azblob"
...
serviceClient, err := azblob.NewServiceClientWithSharedKey(primaryEndpoint, sharedKeyCredential, nil)
containerClient := serviceClient.NewContainerClient(containerName)
blobClient := containerClient.NewBlockBlobClient(blobName)
properties, err := blockBlob.GetProperties(ctx, nil)
log.Printf("error is %+v: %+v", reflect.TypeOf(err), err)
storageError := azblob.StorageError{}
log.Printf("error is azblob.StorageError: %+v", errors.As(err, &storageError))

Expected results

error is *azblob.StorageError: ....
error is azblob.StorageError: true

Actual results: azblob.InternalError

error is *azblob.InternalError: ===== RESPONSE ERROR (ErrorCode=BlobNotFound) =====
Description=, Details: (none)
error is azblob.StorageError: false

And I didn't find a way to get the original error code - azblob.StorageError / ErrorCode

Thank you!

@zezha-msft could you kindly have someone look into this

@mohsha-msft I believe a relevant change just happened but it's not released yet, does it address this issue?

Could you provide a way how to access this StorageError? I'm having the same issue while using 0.4.1 which is released in May.

Hi @deiter!
Azure Core introduced https://github.com/Azure/azure-sdk-for-go/blob/main/sdk/azcore/errors.go#L14 which can be cast using:

var responseErr *azcore.ResponseError
errors.As(err, &responseErr)

this will be available in the next release.

The usage of *azcore.ResponseError has been released in azblob@v0.5.0.
