Product: SharePoint Server 2019
Device & OS: Windows Server
Scenario: Running a PowerShell script to create publishing pages on an on-premises SharePoint environment.
Observed behavior: The script execution halts and throws the error message: 'No parameterless constructor defined for this object.'

Solution 1Recommended

Post the Issue to the Microsoft Q&A Community

Since this error is isolated to SharePoint Server 2019 and a specific cumulative update, escalating to Microsoft Server experts is the most effective path to a resolution.

The 'No parameterless constructor' error often indicates an internal code change within the cumulative update that breaks existing PowerShell cmdlets or .NET calls. Because this is a server-side dependency issue rather than a user configuration error, direct intervention or patching from Microsoft's engineering team is usually required.

Frequently Asked Questions

Why does the 'No parameterless constructor defined' error happen in PowerShell?

This error occurs when a script tries to create an instance of a .NET class or object that requires specific parameters, but none are provided. An update like the July 2024 patch may have modified the underlying SharePoint classes, removing the default parameterless constructor.

Can I fix this error by modifying my AddPublishingPage script?

If the required parameters for the class were changed by the update, you might be able to fix the script by supplying the newly required arguments. However, documentation for such internal changes is often sparse, making it best to consult the Microsoft Q&A community first.

Is SharePoint Online affected by this July 2024 PowerShell error?

No. Based on current reports, this specific AddPublishingPage constructor failure is isolated to SharePoint Server 2019 on-premises environments following the July 2024 cumulative update.
