I am new to groovy code. I have a map like this

```
response = {"data":{"--class":"java.util.HashMap","Enabled":false,"Adult":"[recursive reference removed]","TVMA":"[recursive reference removed]","Locks":[false,false,false,false,false,false],"PINEnabled":false,"AdvisoryLocks":[false,false,false,false,false,false,false,false,false,false,false,false],"safeSearch":"[recursive reference removed]","RatingLocks":[false,false,false,false,false,false]},"success":true}

```

Using groovy code I want to check the presence of the following keys: 

```
Enabled,
Adult,
TVMA,
Locks,
PINEnabled,
AdvisoryLocks,
safeSearch,
RatingLocks,

```

I am using the following code:

```
 for ( data in response.data ) {
            println("-----------------------------------------")       

            assertNotNull(data.Enabled)
            assertNotNull(data.Adult)
            ;;;;;;
            .......
            }
        Am getting groovy.lang.MissingPropertyException: No such property: Enabled

```

How can I check the presence of the above keys from response map using groovy?
