I'm trying to disable a scheduler task during Release pipeline. I use your Disable Windows Scheduled Task. The configuration is as follows: obraz

I get the error:

I tried various combinations:

I always get some kind of errors. Is there any example of correct configuration and if something should be set up additionally on a target machine?

My configuration:

Thanks!

Thanks for reporting the issue and giving such detailed info @Episodex . Can you run the pipeline one more time with Debug mode enabled and paste the script output here please.

To initiate debug mode for an entire release, add a variable named System.Debug with the value true to the Variables tab of a release pipeline.

deadlydog commented 4 years ago

After some Googling, I suspect this may actually be a bug with PowerShell 4. Are you able to update PowerShell on that Windows Server to 5.1?

Episodex commented 4 years ago

Thank you for very fast reply! I enabled the debug and learned from the log that despite the error the step does what it's meant to do. So it's disabling the task. Also then I added Stop and Enable steps later and they also work despite throwing same errors, so I set them to Continue on error and whole pipeline works. The downside is that it's marked as "Partially succeeded".

There are a lot of PS scripts used on this server and updating PS there could be risky. Below is complete debug log from Disable task step:

I looked over the code and it seems I might not even need to call that ExpandString method at all, so I'm going to look at just removing it. Unfortunately all of my unit tests are broken because Pester released v5 and it has a ton of breaking changes, so I'll need to get that fixed up first before I'm confident in removing the ExpandString call. I'll report back once I've been able to properly test out the changes.

I've just pushed out v2.0.23 of the extension which I believe should correct this issue. Let me know if you still see the error or not. Thanks :)

I've just tested it and indeed now the pipeline succeeds :). Thanks for great support!
