Image result for sitecore powershell

Recently I’m trying to export content from Sitecore with Sitecore PowerShell Module. If you have never used this module before, you can read the documents here.

I created a PowerShell script in Sitecore, and everything is working smoothly and fine, until I created a admin page for calling the scripts programmatically.  The scripts were triggered, however the file was not generated.  At very beginning I thought it was caused by insufficient permission for creating files.  So I tried to give everyone read/write permission.  Unfortunately, it was still failed with no exceptions.  

After investigating the logs, I found that it was throwing an error.  It was a bit strange to me, as if I run the scripts in Sitecore. It exports files successfully. However, if I run the scripts via the admin page I created, it fails (as shown in screenshot below)


The error message was a bit misleading.  After a few times trial and error , I realized that when the scripts are called from external application, Sitecore PowerShell doesn’t know the context.  Thus, I added “Set-Location” for all the scripts, and run “export” again, it started working!
