Are you using newest version of the plugin? I remember this issue already was fixed.

[Sunny Patel]

No its 3.3.1 and I see the latest version on github is 4.x
Let me see how to upgrade the plugin in pycharm.

Thank you for your hard work.

[Sunny Patel]

I was using pycharm 2019.3 which would auto update the plugin as it said that the newer version was incompatible.
So I upgraded to pycharm 2020.2 and the plugin works fine.

Thank you
