Is this Json response from content-filter?

Hi guys,
I’m experimenting with the content-filter endpoint just to understand how output label works.
Is this JSON response correct?
“top_logprobs”: [
{
“0”: -13.397785,
“1”: -4.493209,
“2”: -0.011250146,
“3”: -14.8568,
" 2": -15.379619 // there’s a space ?
}
]

Thanks in advance!
