Bundle, manifest.json, driver value for JSVM/javascript

I want to bundle some JSVM middleware components (js files)

What value do I put in for “driver” in the manifest.json

The only example is “python” listed here: https://tyk.io/docs/customise-tyk/plugins/rich-plugins/plugin-bundles/

Is it “otto”?

Hello!

You are right, it is “otto”.
