jsonpath_ng.exceptions.JsonPathLexerError - Unexpected character: ?

[FlanniganColum]

Hey. So i am trying out the jsonpath_ng for the first time and by using the below sample code i am getting the below error. while using the site "https://www.javainuse.com/jsonpath" i am validating the jsonPath syntax and it works fine, do i need to escape the question mark or is this a known issue, and if so do you know a workaround

Package Version

---

jsonpath-ng 1.6.0

os="Linux"
data = module.zabbix.get_service(value=os, filter="name")
jsonpath_expression = parse("$.[*].parents[*][?(@.name == 'Sample')].serviceid")
for match in jsonpath_expression.find(data):
print(match.value)

After reading more i noticed i made a mistake and was not using the .ext, so i have fixed that and now the error i get is. Course the ultimate plan is to have the path name lookup a variable so i can using it dynamically.

Actually i found the solution if i adjusted the syntax to the below it worked for me

jsonpath_expression = parse("$.[*]['parents'][?(@.name == 'Sample')].['name']")
