What is the version of powershell used on the MID Server. Is it version 2.0 or higher.

[mayank_ihs]

Hello Yes, 

The version is 4.0. I was also suspecting the same but that's not the issue. 

Can it be something else ?

Thanks

HI,

Have you modified the PSScript.ps1 Script file in serviceNow or on MID Server?

Thanks,
Ashutosh

[mayank_ihs]

Nope , The PS file has not been touched, Discovery works fine for many of the Servers but fails for some with these errors and HI support is working on the root cause. We have a case open and they don't have a fix for this one yet. 

Thanks
