Description eR@SeR 2021-01-03 23:48:02 UTC

Hello,

Updated json-path-2.5.0.jar in latest nightly is not executing some json path expressions:

$.store.book[?(@.price>=8 && @.category=~ /.*reference.*/)] OK
$.store.book[?(@.price>=8 || @.category=~ /.*reference.*/)] OK
$.store.book[?(@.category=~ /.*reference.*/ && @.price>=8)] doesn't work
$.store.book[?(@.category=~ /.*reference.*/ || @.price>=8)] doesn't work
$.store.book[?(@.category=~ /.*reference.*/ && @.price=~/-.+/)] doesn't work
$.store.book[?(@.category=~ /.*reference.*/ || @.price=~/-.+/)] doesn't work

Example JSON can be found here: https://github.com/json-path/JsonPath#path-examples

Error in JSONPath Tester in VRT is "Exception: Expected character: )" and when test is executed "ERROR o.a.j.e.j.j.JSONPostProcessor: Error processing JSON content in JSON Extractor, message: Expected character: )"

One of my tests relies on two regexes like $.store.book[?(@.category=~ /.*reference.*/ && @.price=~/-.+/)] so extractions that were OK in 5.3, in newest nightly are failing. If two regexes are a must, there is no workaround I guess. Please consider reverting to json-path-2.4.0.jar until the issue is resolved.

Someone already reported it - https://github.com/json-path/JsonPath/issues/658

P.S. Nice to see Jayway JsonPath project gets revived after few years of inactivity. Looking forward to seeing the resolution of https://github.com/json-path/JsonPath/issues/287 :)

That seems to be https://github.com/json-path/JsonPath/issues/658

The stacktrace on that error would be:

    Revert json-path to version 2.4.0

    The newer version 2.5.0 has a bug https://github.com/json-path/JsonPath/issues/658
    which surfaces when using regexes in the expressions.
