How to fix "Failed to instantiate a processor of type '"Sitecore.Xdb.MarketingAutomation.Processing.EventProcessor"'"

Question

Marketing Automation is not working. When I check log in [xconnect]\Website\App_data\jobs\continuous\AutomationEngine\App_Data\Logs I have found this below error: Failed to instantiate a processor of type '"Sitecore.Xdb.MarketingAutomation.Processing.EventProcessor"'

I have searched a lot but don't find anything related to fixing this issue.

Answer 1

Please check SSL certificate of {website}.xconnect in IIS. Also please check the license file of .\Website\App_data\jobs\continuous\AutomationEngine\App_Data and thumbprint of .\Website\App_data\jobs\continuous\AutomationEngine\App_Config\ConnectionStrings.config file. There might be some problem there.

Answer 2

The fix for me on this issue was to grant permission to IISUser on the xConnect certificate.

Steps:

• Right click on certificate
• Click on manage private keys and grant permission to IISUser.

Answer 3

I checked Event Viewer and there were two "strange" errors:

ISAPI Filter 'C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\\aspnet_filter.dll' could not be loaded due to a configuration problem

Could not load all ISAPI filters for site 'SITECORE911.XCONNECT'. Therefore site startup aborted.

I don't know how but in IIS the path to ISAPI filter was with two slashes

v4.0.30319\\aspnet_filter.dll

instead of

v4.0.30319\aspnet_filter.dll

This was my solution. This fixed XConnect site, it started to run and error "This configuration has not been initialized. Please call the initialize method before using it" disappeared due to it.
