Node-webform analysis error

Hello! I use webform-8-rc16 and webform-analysis-beta6. When I try to get analysis for any of my node-webforms I get the following error: "The website encountered an unexpected error. Please try again later."
After that I see two error messages in site log:

The first is

and the second is:
