Initialize-ACMEVault throws Error resolving type specified in JSON

[jozefizso]

I am trying to create a new vault profile. When the Initialize-ACMEVault command executes it throws the Error resolving type specified in JSON 'ACMESharp.Vault.Profile.VaultProfile, ACMESharp.Vault'. Path '$type', line 2, position 67. exception.

$env:ACMESHARP_VAULT_PROFILE = 'vault1_profile'
$vault = 'c:\vault\vault1'
$vaultParams = @{ RootPath = $vault; CreatePath = $true }
Set-ACMEVaultProfile -ProfileName $env:ACMESHARP_VAULT_PROFILE -Provider local -VaultParameters $vaultParams -Force
Initialize-ACMEVault -BaseService LetsEncrypt-STAGING -Force -VaultProfile $env:ACMESHARP_VAULT_PROFILE

Initialize-ACMEVault : Error resolving type specified in JSON 'ACMESharp.Vault.Profile.VaultProfile, ACMESharp.Vault'. Path '$type', line 2, position 67.
At line:1 char:1
+ Initialize-ACMEVault -BaseService $service -Force -VaultProfile $env: ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [Initialize-ACMEVault], JsonSerializationException
    + FullyQualifiedErrorId : Newtonsoft.Json.JsonSerializationException,ACMESharp.POSH.InitializeVault

The vault profile file looks like the others:

{
  "$type": "ACMESharp.Vault.Profile.VaultProfile, ACMESharp.Vault",
  "Name": "vault1_profile",
  "ProviderName": "local",
  "ProviderParameters": null,
  "VaultParameters": {
    "$type": "System.Collections.Generic.Dictionary`2[[System.String, mscorlib],[System.Object, mscorlib]], mscorlib",
    "CreatePath": true,
    "RootPath": "c:\\vault\\vault1"
  }
}

Some application installed Newtonsoft.Json into GAC. PowerShell was loading the GAC version of assembly and it caused the issue. Removing it from GAC fixed the problem.

gacutil -u Newtonsoft.Json

Uninstalled: Newtonsoft.Json, Version=7.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed, processorArchitecture=MSIL

Thanks for troubleshooting this, I've added you issue details to the FAQ so others can benefit from your experience.

I'm getting this same error and there is no assemblies found matching Newtonsoft.Json.

Navigate to your local app data folder, and go to ACMESharp\vaultProfiles. In there, you will find a file that represents your vault profile in JSON. Remove the first '$type' node for the VaultProfile type, and it solved the issue for me.

If you look at the ACMESharp.JsonHelper generic Load method for streams, the JSON deserializer has serializer settings type name resolution set to automatic, which that behavior changes between IDEs. It might be better to have that setting set to not use any type name resolution based on declared .NET types, but I haven't tested changing it.
