Groovy Script how to get data from response

Hello.

This is my first time using SOAPUI. I'm testing openweathermap api and I need to write groovy script which log 'Checking weather in ' + name

I wrote something like this but it's log Checking weather in null 😞

def json = new groovy.json.JsonSlurper().parseText(context.response)
context.testCase.setPropertyValue('name', json.coord.name.toString())
log.info "Checking weather in " + json.coord.name

Response:
