```$..[?(@.name=='is_literate')]``` expression works completely fine on https://jsonpath.com/ but it throw an error while using this expression at `jsonpath-ng`

Hello everyone,
I am facing an issue with phasing data. My expression looks like $..[?(@.name=='is_literate')] it throws error. Also, I tried $[?(@.name=='is_literate')] this time, this does not throw any error, but I did not get the expected value. Which is given as follows. I tried it at https://jsonpath.com/, it works fine with $..[?(@.name=='is_literate')] expression.

Note: I have the name of the label, but I don't have label. I need a label based on the name value.

[
  {
    "control": {
      "appearance": "quick"
    },
    "children": [
      {
        "name": "is_literate_1",
        "label": "साक्षर"
      },
      {
        "name": "is_literate_0",
        "label": "निरक्षर"
      }
    ],
    "name": "is_literate",
    "label": "${full_name}: साक्षर कि निरक्षर ?",
    "bind": {
      "required": "true"
    },
    "type": "select one"
  }
]

I am attaching the JSON file for reference. I would appreciate it if someone could resolve this issue. Thank You.
