[BUG] Getting Exception: Cannot convert null to type "System.DateTime".

[MrZeeEs]

On Windows 10 Pro is installed:

SecretManagement.Hashicorp.Vault.KV/2.0.0 Microsoft.PowerShell.SecretStore/1.0.5 Vault 1.9.2. PowerShell7

I have started Vault in DEV mode and only token authentication is set up.

Logging has revealed that there is a problem with System.DateTime conversion and Token's expiration datetime.

The whole debug report:

Expected behaviour: valid token is retrieved, no datime error happens

Thanks for submitting this @MrZeeEs. I believe that the issue here is that you are using the Root token and that does not have an expiration time stamp, which is causing this error. Should have a fix pushed out to the Gallery soon.

[joshcorr]

Please try pulling the latest preview version from the Gallery version 2.0.1-Preview

Install-Module -Name SecretManagement.Hashicorp.Vault.KV -AllowPrerelease

This should fix the issue you were facing.

@MrZeeEs did you have a chance to try the code in the Preview branch?

Tested today 2003-08-25 Vault 1.13.0 SecretManagement.Hashicorp.Vault.KV 2.0.1 Preview Powershell 7.2.13

Auth with root token still returns "System.Management.Automation.PSInvalidOperationException: Unable to run Test-SecretVault on vault"
