PSPKI v4.2.0 Module cannot find type [PKI.OCSP.OCSPRequest]

[PChipVIA]

When running Get-EnterprisePKIHealthStatus with version 4.2.0 on PowerShell 5.1, it gives out this error.

DEBUG: Entering OCSP validation routine...
DEBUG: URL: http://ocsp.******.***/ocsp

This error does not happen with v3.4.x on Powershell 5.1. I thought it was due to an error while upgrading so have installed the module on another computer which never had PSPKI before and give out the same error.

Thanks for reporting! The fix is added and will be available in v4.3. For now, you can manually change Get-EnterprisePKIHealthStatus as in this commit: https://github.com/PKISolutions/PSPKI/commit/475e2ab6794bbbe52762f9baf8f1d32bc35c80c5
