Unable to Download Blob Programmatically - azure

Question

We have multiple blobs in an azure storage container, when we use powershell to download the blobs (files), 8 out of the 9 files download, however the 9th one fails. There is absolutely nothing different about this file, the only thing I've noticed in the blob properties the "content MD5" is blank, however the other 8 have a value. Not sure what this is or if it has anything to do wit it, I was hoping someone could shed some light as to why this is one file is not downloading..
Thanks in advance :)

Try below code for downloading files from Azure Blob
function Get-DLLFile
{
param(
[Parameter(Mandatory=$true)] [string] $connectionString,
[Parameter(Mandatory=$true)] [String[]] $blobsName,
[Parameter(Mandatory=$true)] [string] $container,
[Parameter(Mandatory=$true)] [string] $filePath
)
Try
{
foreach ($blobName in $blobsName)
{
$file = $filePath + $blobName
$fileAvailable = Get-Item -Path $file -ErrorAction SilentlyContinue
if($null -eq $fileAvailable)
{
$ctx = New-AzureStorageContext -ConnectionString $connectionString
New-Item -Path $filePath -ItemType Directory -Force | Out-Null
Get-AzureStorageBlobContent -Blob $blobName -Container $container -Destination $filePath -Context $ctx -Force | out-null
}
}
}
Catch
{
$_.Exception.Message
}
}
Get-DLLFile -blobsName "File1.csv","File2.json" -container "myContainer" -connectionString "$(BlobConnectionString)" -filePath "$(System.DefaultWorkingDirectory)/Download"
Hope this should work, if not Please share the exception you are getting.
