Example of #code helper for grpc mocks

[AndersSoee]

all attempts so far when using the #code helper in grpc mocks ends with
error: Unexpected end of JSON input
example:

{{#code}}
(()=>{
    return '{ "foo": "bar"}'
})();
{{/code}}

Could you provide an example of how to use this?

@AndersSoee were you ever able to make this work?
