How to pass parameter in a JSON file in karate

Question

I have my request body in a *.json file and same *.json request body with different parameters is used in multiple test scenarios. How to pass variables in this scenarios.

I tried below

* def requestBody = call read ('successScenario.json') { id: 'U123', age: 23, date: currentDate }
And request requestBody

Please note I can't use examples as one of my variable is currentDate function so how to pass currentDate variable via examples.

This is not working. If I don't pass parameters here it works fine. I don't want to define these parameters in karate-config.js file as it is scenario dependent variables.

When I use above in *.js file it works fine but the response body is JSON i can't make a *.js file for that.

Please note that there is no such thing as call read('some.json'). In other words, JSON is not something you can call.

Please take some time to read this part of the docs: https://github.com/karatelabs/karate#call-vs-read

If you want to "data drive" a JSON file, use "embedded expressions".

This is explained well here: https://stackoverflow.com/a/50093102/143475
