i have a response like this: 

```
{
  "Team:14051898": null,
  "59a0a29fe4b04de817c2a635": {
    "eid": "abc123",
    "name": "Chris"
  },
  "57dc07aae4b00768fe90cbf7": null,
  "Team:15199": {
    "eid": "abc123",
    "name": "Christin"
  },
  "59c53c15e4b066f69a1180d4": {
    "eid": "abc123",
    "name": "Michae"
  },
  "589cace8e4b0b32006e03299": {
    "eid": "abc123",
    "name": "Jay"
  },
  "59e0e2eae4b0c0e023297a2f": null
}

```

i need to find the length (no:of teams) in it. I tried using:

```
* string expression = 'Object.keys(response).length'
* def result = karate.eval(expression)
* print result

```

And also $.length and few other options. Please help me with this.
