Could not create instance of type: Sitecore.ContentSearch.Azure.CloudSearchProviderIndex. No matching constructor was found

Question

Currently in progress of upgrading from Sitecore 8.1 to 8.2 update 7. So I'm currently converting existing indexes from luecene to Azure search, I have done all the basic steps like, disabling all the lucene related files and enabling Azure config files. Default indexes like master, web are reindexed in Azure successfully.

Issue is with the custom configs. I created custom configs based on the default Azure configs and also other recommendations found online like,

Creating a new index in Azure Search for Sitecore 9 Helix structured

But still i get the below error when I open indexing manager in Sitecore. Please let me know if I missed any of the mandatory setting.

Server Error in '/' Application. Could not create instance of type: Sitecore.ContentSearch.Azure.CloudSearchProviderIndex. No matching constructor was found.

Answer 1

You have the wrong type in ContentSearchIndexConfiguration. Change from

<ContentSearchIndexConfiguration type="Sitecore.ContentSearch.Azure.CloudSearchProviderIndex, Sitecore.ContentSearch.Azure">

to

<ContentSearchIndexConfiguration type="Sitecore.ContentSearch.Azure.CloudIndexConfiguration, Sitecore.ContentSearch.Azure">

The best way to debug these kinds of issues is to compare to default index configurations - in your case Sitecore.ContentSearch.Azure.DefaultIndexConfiguration.config and Sitecore.ContentSearch.Azure.Index.Master.config
