JSONPath Query in array

Here is my JSON :

[
  {
    "Data": [
      {
        "Count": null,
        "TimeStamp": "2023-03-18T09:56:00Z",
        "Average": null,
        "Maximum": 0.4,
        "Minimum": null,
        "Total": null
      }
    ],
    "Name": {
      "LocalizedValue": "DTU used",
      "Value": "dtu_used"
    },
    "Unit": "Count"
  },
  {
    "Data": [
      {
        "Count": null,
        "TimeStamp": "2023-03-18T09:56:00Z",
        "Average": null,
        "Maximum": 20.0,
        "Minimum": null,
        "Total": null
      }
    ],
    "Name": {
      "LocalizedValue": "DTU Limit",
      "Value": "dtu_limit"
    },
    "Unit": "Count"
  }
]

I am trying to get the value of Data.*.Maximum in the same array where Name.Value = 'dtu_limit'.

I can get the values of Maximum with $.*.Data.*.Maximum but I don't know how to filter.

I tried things like this but that doesn't work : $.*[?(@.Name.Value == 'dtu_used')].Data.*.Maximum

Please help !

...doesn't work : $.*[?(@.Name.Value == 'dtu_used')].Data.*.Maximum

You need to remove that first .*. So either:

$[?(@.Name.Value == 'dtu_used')].Data.*.Maximum

or

$[?(@.Name.Value == 'dtu_limit')].Data.*.Maximum

Depending on which value you want to filter by.
