myproject.localhost throw except because pageTile is null in SitecoreController.cs

Question

I'm running up.ps1 in step 7 of Create the MyProject solution in the Sitecore 10 Getting Started Template. While id.myproject.localhost and cm.myproject.localhost work fine for me, but myproject.localhost throw a exception caused by pageTile is null.

Do you know what problems? How can I solve it?

Answer 1

You need to publish the website for seeing your changes on the cd instance. If you will see the Test the MyProject solution section on the same URL - https://doc.sitecore.com/xp/en/developers/100/developer-tools/walkthrough--using-the-getting-started-template.html#test-the-myproject-solution it is pointing to publish the website page - https://doc.sitecore.com/xp/en/developers/100/developer-tools/publish,-run,-and-test-the-getting-started-template-projects.html

To publish the Platform project:

1. in Content Editor, on the Publish tab, below the Publish icon, click the black arrow () and click Publish site.
2. In the Publish Site window, select Smart publish and click Publish.

The RenderingHost project uses dotnet watch which automatically compiles and deploys all changes to the myproject_rendering_1 container. You can visit the rendering host page at https://www.myproject.localhost/, and you can see the rendering host log by clicking the container in Docker Dashboard or by running this PowerShell command from the MyProject folder:

docker-compose logs -f rendering
