I have followed the installation instructions on the official Geonode page to install it on ubuntu(18.04.4) and when I finish it I have published a Layer but when I click on Openlayers preview of the Geoserver layer,it viewed with this error:
HTTP ERROR 500

I don't know what is the problem, it must be from Geoserver because I already used the layer on another computer with Geoserver and it works perfectly.
The bottom of the error log is:
