Import har content plugin not working

Hello all,

In all the previous ReadyAPI versions, we had been using the plugin mentioned below, which imported .har files to SoapUI Pro and created a project from its content.
After the 3.8.1 upgrade, the plugin stopped working. Does anyone have a workaround for this or is there any other plugin available?
