How to replace the "GET" function in the new API?

Hello everyone,
I am trying to adjust my app with the new Freshdesk api and have the following bits of code that throw an error and are no longer supported.
This is the error:

And these are the bits of code.

The error is about your JSON being ‘Undefined’. So, the best guess is your query string is missing.

[Freshdesk](https://Query/Filter API Doc)

@Alex_Grossi The invocation seems to be wrong. It should be

client.request.invokeTemplate(requestTemplateName, {
  context: {},
  body: JSON.stringify(body)
});
