I always get this error: OpenError: The background process reported an error with the following message: .
I’ve ran this script on the target server with the same user as the Tentacle is running with, and it worked fine. Do you have any clue what might cause this?
here is the raw Octopus log, with variable debugging turned on, I have altered the passwords, user names and server names: octoraw.log.txt (34.8 KB)
To answer your questions:
originally I’ve run this script in the script console, and the variables are just local ones, nothing coming from the project, tenant or variable set level, now I added it to a project to be able to turn on variable logging,
no, the tentacle user is different from the user I’m trying to run the command with, see: raw log,
After a quick test, it looks like the default service account for tentacles, NT AUTHORITY\SYSTEM, does not carry high enough permissions to invoke System.Management.Automation. I was able to run the script as a different user on my tentacle in my test environment. See below:
as I mentioned before, my tenancle is running as a dedicated domain user, which is a member of the local Administrators group on the target server. Are there any other rights I might have forgotten to add?
I did quite a bit of research and asked around internally. Unfortunately, was unable to find a definitive answer here. It may be worth checking the windows event logs to see if the “access denied” is logged in a way that is helpful. If all else fails, contacting Microsoft directly might be an option as well.
If I can assist with anything else, please let me know.
what bothers me is that I tried to run the script on the server with the tentacle user from a normal powershell and it is working. Whenever I run the script from Octopus I get the error and the below info logged in Windows System Log:
Application popup: powershell.exe - Application Error : The application was unable to start correctly (0xc0000142). Click OK to close the application.
There may be something going on with interactive PowerShell vs non-interactive.
Here’s a StackOverFlow post with a bit of information on this topic:
If you haven’t already, I still recommend contacting Microsoft directly to inquire about the permissions needed to prevent System.Management.Automation from throwing an Access is denied error.
If I can assist with anything else, please let me know.
