Fix for index not found error while installing Commerce Connect 7.2

I found a missing step in the Sitecore Commerce Connect 7.2 Installation Guide that I’d like to share:On step 5 of the “Integrating an External Commerce System – Creating a Product Repository” guide you are instructed to Synchronize All Products, however when I reached this step I received the following error:

Upon further inspection in the Sitecore log file, I found the following:

Exception: System.Reflection.TargetInvocationExceptionMessage: Exception has been thrown by the target of an invocation.Source: mscorlibat System.RuntimeMethodHandle.InvokeMethod(Object target, Object[] arguments, Signature sig, Boolean constructor)at System.Reflection.RuntimeMethodInfo.UnsafeInvokeInternal(Object obj, Object[] parameters, Object[] arguments)at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture)at System.Reflection.MethodBase.Invoke(Object obj, Object[] parameters)at (Object , Object[] )at Sitecore.Pipelines.CorePipeline.Run(PipelineArgs args)at Sitecore.Jobs.Job.ThreadEntry(Object state)Nested ExceptionException: System.ArgumentExceptionMessage: Index commerce_products_master_index was not foundSource: Sitecore.ContentSearchat Sitecore.ContentSearch.ContentSearchManager.GetIndex(String name)at Sitecore.Commerce.Data.Products.ProductRepository.GetEntityItems(Item repositoryItem)at Sitecore.Commerce.Data.Products.ArtifactRepository`1.GetEntities(Item root)at Sitecore.Commerce.Pipelines.Products.GetSitecoreProductList.GetSitecoreProductList.Process(ServicePipelineArgs args)at (Object , Object[] )at Sitecore.Pipelines.CorePipeline.Run(PipelineArgs args)at (Object , Object[] )at Sitecore.Pipelines.CorePipeline.Run(PipelineArgs args)at Sitecore.Commerce.Services.ServiceProvider.RunPipeline[TRequest,TResult](String pipelineName, TRequest request)at Sitecore.Commerce.Services.Products.ProductSynchronizationProvider.RunPipelineBody[TRequest,TResult](String pipelineName, TRequest request)at Sitecore.Commerce.Services.Products.ProductSynchronizationProvider.SynchronizeProducts(SynchronizationRequest request)

There is an easy fix for this, simply enable your “Sitecore.Commerce.Products.Lucene.Index.Master.config” file and verify all of its settings.

Once completed, re-run the product synchronization tool and you can continue with the rest of your Sitecore Commerce Connect 7.2 installation.
