Issue in generate SignedUrl method for blobs in blob storage

The method generatePreSignedURL is supposed to to give signed url with relevant SAS token permissions to a blob in blob storage. When trying to use this with relevant data-partition and other parameters , results in exception with message "The argument must not be null or an empty string. Argument name: storageSharedKeyCredentials". I assume this is because the BlobServiceClient used is generated of DefaultAzureCredential and this might not be having required iam. However when I've tried to use BlobServiceClient generated using StorageSharedKeyCredential based on blob storage account name and account key like this , I could generate SignedURL
