What happened?

A module that installs successfully to DNN 9.x sites fails to install on a DNN 10.2.0 site. The module project was rebuilt for .NET 4.8 and Nuget references were updated to DNN 10.2.0, but no code or manifest file changes were made.

The module contains a <page type="Admin" common="true"> element within the <desktopModule> element in the manifest.

The installation fails with with an error that appears to come from the attempt to add the module to a page under the Admin menu.

Steps to reproduce?

1. Install any module that contains a <page type="Admin" common="true"> element within the <desktopModule> element in the manifest. For example:

            <page type="Admin" common="true">
              <name>Visitors Online</name>
              <icon>~/Icons/Sigma/Sitemap_16X16_Standard.png</icon>
              <largeIcon>~/Icons/Sigma/Sitemap_32X32_Standard.png</largeIcon>
              <description>Website visitors currently online</description>
            </page>

Have you by chance tested this on any other 10.x versions? Otherwise I'll try to test/validate tomorrow

Sorry, no. I upgraded to v10.2.0 from 9.x directly.

@lanthonyneville Is this on a portal that is a non-english language? Any chance of getting an installer for the module in question?

No, its US English. The module is the DNN Community Web Analytics module, but with a customisation to the manifest: the <page> element (sample above) is added within the <desktopModule> element for both the "Dnn.WebAnalytics" and "Dnn.VisitorsOnline" module packages.

Not sure if this is relevant, but the module was already installed in the DNN 9.x site, then I performed the upgrade to 10.2.0, then I tried rebuilding the module from source using .NET 4.8 and Nuget references updated to DNN 10.2.0 (I think this wasn't actually necessary, but I wanted to make sure it was not using deprecated APIs), then I installed my updated version. It was at this point that I got the install error.
