Azure Key Vault Set Secret from PowerShell- Pattern Match Exception

Please post the code you're using.

1. Azure Powershell is outdated (i.e. it still works, but it's no longer supported)
2. Use the newer Az module (azpsmigrate
3. The secret is supposed to be a secure string. Is that what you're using? If not, see the help for the cmdlet and follow the examples given there.

Here is the code along with error i am using. Thanks for the response
$inputfile = Import-Csv C:\BCP\inputcsv.csv

foreach($inp in $inputfile)

{

$Name = $inp.Name

$secretvalue = $inp.secretvalue

$Contenttype = $inp.Contenttype

$Tags = @{$inp.TagName = $inp.TagValue}

$Secret = ConvertTo-SecureString -String $secretvalue -AsPlainText -Force

set-azkeyvaultsecret LTLkeyVault -Name $Name -SecretValue $secret -ContentType $Contenttype -Tag $Tags

}

The name of the secret is the problem. You cannot have dashes or other special characters in the name except for $. It is not referring to the secret Value.
