Execution of JavaScript Response Handler Failed: Cannot find engine to execute JavaScript.

Was trying out http client finally and was testing out the response object I get

Execution of JavaScript Response Handler Failed: Cannot find engine to execute JavaScript.

I've selected various javascript engines from the settings dialog under languages and frameworks

I added the project directory and select ECMA 5.1 invalidated caches and restarted and still the same message.

Built a couple of new projects, tried with and without setting the folder

I must be missing something simple, critcal, and in a fully featured project like this, somewhere subtle.

This is the new 2019.1

Oh, and if you are curious, in the end I whittled it down to this

> {%

client.log("wth")

%}
