How to use a variable in JsonPath filter

Question

I'm attempting to use a variable in the RHS of an JsonPath filter expression in a Karate test, similar to this:

* def name = 'A Name'
* def ids = $response[?(@.name == '#(name)')].id

If I use the literal string 'A Name' in the RHS of the expression it works as expected.

I've tried various ways to get the variable to evaluate: '<name>', "#(name)", etc.

I suspect it is because I'm mixing JsonPath parsing with Karate parsing perhaps?

Read this first: https://github.com/intuit/karate#rules-for-embedded-expressions

And what you are looking for is this: https://github.com/intuit/karate#jsonpath-filters

* def ids = karate.jsonPath(response, "$.kittens[?(@.name=='" + name + "')].id")
