Using match each contains for json array items assertion

I would like assert that the price gross is greater than equal to price_net. Can you please tell me how can I achieve this correctly ? This is what I have done atm.
Scenario: Testing
* def response =
"""
{
"prices": [
{ "price_net":"10.50", "price_gross":"12.25" },
{ "price_net":"10.50", "price_gross":"12.25" },
{ "price_net":"10.50", "price_gross":"12.25" },
{ "price_net":"10.50", "price_gross":"12.25" },
{ "price_net":"10.50", "price_gross":"12.25" },
{ "price_net":"10.50", "price_gross":"12.25" }
]
}
"""
* match each response.prices[*].price_gross == '#? _ >= 0 && _ >= response.prices[*].price_net'
I think the '*' inside the assertion statement is the problem. Because when I run this
* match response.prices[0].price_gross == '#? _ >= 0 && _ >= response.prices[0].price_net'
it works fine. Please suggest. Thanks in Advance.
