Rebuilding link database in Sitecore

Question

I am getting the below error while rebuilding link database in Sitecore 8.1 (Initial release).

Object reference not set to an instance of an object. [NullReferenceException: Object reference not set to an instance of an object.] Sitecore.Shell.Applications.Dialogs.RebuildLinkDatabase.RebuildLinkDatabaseForm.CheckStatus()

any suggestion to fix the error?

Thanks, Karthik

Sitecore 8.1 was released over 5 years ago, tons of improvements were made since then. Product seem to be out of mainstream support, hence Sitecore would not assist you here.

You could do following:

1. Download iLSpy - reverse engineering tool to see the source code
2. Inspect how RebuildLinkDatabaseForm class, CheckStatus method is implemented; where NRE could bubble up
3. Recompile code with either additional logging & improved NRE handling & wire it up via wwwroot\sitecore\shell\Applications\Dialogs\RebuildLinkDatabase\RebuildLinkDatabase.xml file
