Read Karate config from YAML - karate

Question

I would like to define environment-specific properties in a .yml/.yaml file. Therefore I created the following test.yaml:
baseUrl: 'http://localhost:1234'
Next, I wrote this karate-config.js:
function() {
var env = karate.env;
if (!env) {
env = 'test'; // default is test
}
// config = read(env + '.yaml')
var config = read('/home/user/git/karate-poc/src/test/java/test.yaml');
// var config = read('test.yaml');
// var config = read('classpath:test.yaml');
return config;
}
As seen here https://github.com/intuit/karate#reading-files the read() function should be known by Karate, however I'm not sure if this only applies to .feature files or the karate-config.js too.
Unfortunately, none of the above read()s work, as I'm getting this error:
Caused by: com.intuit.karate.exception.KarateException: javascript function call failed: could not find or read file: /home/user/git/karate-poc/src/test/java/test.yaml, prefix: NONE
at com.intuit.karate.Script.evalFunctionCall(Script.java:1602)
I'm sure that the file exists and is readable.
Am I doing something wrong or is my approach not supported? If it's not supported, what would be the recommended way to read the configuration based on the environment from a YAML file (once) in order to use it in (multiple) .feature files?
Thank you very much

In JS, use the karate object, which is explained here: https://github.com/intuit/karate#the-karate-object
So this should work:
var config = karate.read('classpath:test.yaml');
