[Python] $..[?(@.name=='is_literate')] expression works completely fine on...

I am facing an issue with phasing data using jsonpath-ng. My expression looks like $..[?(@.name=='is_literate')]. I tried it at https://jsonpath.com/, it works fine with $..[?(@.name=='is_literate')] expression, but when I tried the given expression with jsonpath-ng, it throws an error.

My Python Code looks like following:


from jsonpath_ng.ext import parse
exp = "$..[?(@.name=='is_literate')]"
filter_query = parse(exp)
filtered_data = [match.value for match in filter_query.find(label_data)]
print(filtered_data)

The Error Looks Like


---------------------------------------------------------------------------
JsonPathParserError Traceback (most recent call last)

1 from jsonpath_ng.ext import parse
2 exp = "$..[?(@.name=='is_literate')]"
----> 3 filter_query = parse(exp)
4 filtered_data = [match.value for match in filter_query.find(label_data)]
5 print(filtered_data)

I want following output while using $..[?(@.name=='is_literate')]


[
{
"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"
}
]

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

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