}

Expected Behaviour

Run "Terraform Apply" should create content key policy. In terraform azurerm documentantion appears an example using ASK = "myKeyForFairPlay" I tried in that way and works fine, but the problem is that a real ASK provided by Apple follows a different structure bb566284cc124a21c435a92cd3c108c4 , is an hexadecimal value.
Note: because ASK is a secret I obfuscated it changing some values but leaving same structure

Actual Behaviour

Raise an error:
Error: creating/updating Content Key Policy: (Name "mypolicy" / Mediaservice Name "mediaservicesnew" / Resource Group "rgmediaservices"): media.ContentKeyPoliciesClient#CreateOrUpdate: Failure responding to request: StatusCode=400 -- Original Error: autorest/azure: Service returned an error. Status=400 Code="BadRequest" Message="FairPlay configuration must have ASK. ASK must be 16 bytes."

Steps to Reproduce

1. terraform apply

Thanks @kmorales90 for open this issue. Do you have any documentation about ASK? To check format and specifications please?

[kmorales90]

sure @jcanizalez , check in microsoft documentation how "ASK" is handled in code https://docs.microsoft.com/en-us/azure/media-services/latest/fairplay-license-overview

In section "FairPlay configuration .NET example":
ASK is refered as askHex (Hexadecimal value) and then is a function that basically convert an Hexadecimal to bytes

byte[] askBytes = Enumerable
        .Range(0, askHex.Length)
        .Where(x => x % 2 == 0)
        .Select(x => Convert.ToByte(askHex.Substring(x, 2), 16))
        .ToArray();
