Logbook not showing entries

i am having some problem in my logbook , after the update of home assistant to 0.87 many time i want to see the logbook it takes a lot of time and then says no entried found ,
it was working file before the update ,

how to resolve this issue ?
and is there any way to clear all the old logbook entries if any ?

Any errors in your system log?

There are many errors , i think specially from darksky , but i m not able to resolve them , are they related to this logbook not show ,?

Any relevant errors in the log?

this is my full home assistant error log ,
