Not able to get data in Stats page.

We have installed ClearlyDefined as a docker stack setup.
website , service, crawler and Mongo DB are available as separate containers.
We were able to access the website and perform the Harvest. But not able to see the data in Stats page.
From docker logs we could see 500 error code
