Install Keyword Cloud Plugin

Hello everyone,

I am using OJS I was trying to install KeywordCloud plugin from plugin gallery. However after I click Install, nothing happens and if I refresh page this message pops up

The uploaded plugin archive does not contain a folder that corresponds to the plugin name.

My php error log is like this,

[16-Jul-2020 07:47:15 Asia/Kolkata] PHP Fatal error: Uncaught Error: Call to a member function getProductType() on string in /home/japtronl/domains/
Stack trace:
