We were able to import our products from Sitecore Commerce to the Sitecore CMS (saved as virtual items), and I would like to search for these products using the Sitecore Search. So I rebuild the Sitecore_master_index using the "indexing manager" in the control panel, unfortunately the rebuild stopped after processing the 20000 items and showed me the below error

Job started: Index_Update_IndexName=sitecore_master_index|#Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ArgumentNullException: Value cannot be null.

I assume that the index was crawling all the items until it started to crawl the commerce products and some items are maybe null or something like that.

I hope that someone could help me.

Thanks in advance

I had a similair and what helped me was

  1. Login Sitecore shell -> Desktop -> Content Editor
  2. On Commerce tab click Delete Data templates
  3. On Commerce tab click Refresh Commerce Cache
  4. On Commerce tab click Update Data templates
  5. Go to Index Manager and rebuild the index(Master one).

Best regards Christian
