Complete-ACMEChallenge throws exception when alias begins with a digit

[ghost]

PS> New-ACMEIdentifier -Dns 360fcu.r2graphics.com -Alias 360fcu.r2graphics.com-23jlj23
identifier created successfully

PS> Complete-ACMEChallenge 360fcu.r2graphics.com-23jlj23 -ChallengeType http-01 -Handler iis -HandlerParameters @{ WebSiteRef = "Default Web Site" }

exception thrown as follows:

Complete-ACMEChallenge : Input string was not in a correct format.
At line:1 char:1
+ Complete-ACMEChallenge $alias -ChallengeType http-01 -Handler iis
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Complete-ACMEChallenge], FormatException
    + FullyQualifiedErrorId : System.FormatException,ACMESharp.POSH.CompleteChallenge

If I make sure the alias begins with a letter, the exception does not happen.

That's by design, you can see why over here.
