Kong custom plugin not working

Hello, I’m trying to add a custom plugin to the Kong api gateway in a docker container. Plugin written in javascript language is successfully added to the “/usr/local/kong/js-plugins” path as per docs. however, when the container is running my other existing plugins in kong works just fine but the custom plugin does not. Can someone help me out figuring out the issue ?

//small snipet of kong.conf file:
plugins = KongPlugin

Check this blog post from Kong, they have a good tutorial on writing and configuring JS custom plugin. Building a Kong Gateway Plugin with JavaScript | Kong Inc.
There are several configuration lines that you need.
Also, I think you plugins line should be
plugins: bundled, KongPlugin
But take a look at the blog post for details
