Exception is thrown when a page is visited by robots

  • Search engines might not index pages that have Commerce campaigns and goals assigned or triggered via code, because they cannot access them. The exception is thrown because Commerce Connect does not cover scenarios when robots are involved in site browsing. According to the Sitecore Analytics design, such visitors are skipped. However, Sitecore Commerce invokes the Analytics API for search engine robots, which results in the issue. The following message might appear:

    Exception: System.NullReferenceException
    Message: Object reference not set to an instance of an object.
