Karate 1.20 move to graalvm breaks usage of variables in multi-value parameters

[LanDinh]

Code of the type

@name=testScenario
Scenario: example scenario

* def foo = 'foo'
* def bar = 'bar'

* url 'example.com'

Given param test = [#(foo), #(bar)]

fails with the error message

org.graalvm.polyglot.PolyglotException: SyntaxError: Unnamed:1:1 Expected an operand but found error
[#(foo), #(bar)]
 ^

This used to work fine with Nashorn, and using variables in json objects (so using { ... } is still working fine. I don't know if it's an issue with the param keyword, or with the fact that we use [ ... ] here - this is breaking our tests.

@LanDinh
Enclosing your array in parenthesis should work:

Given param test = ([foo, bar])

This approach is also more concise, since you don't need to use the #() syntax for each variable.

agree with @nathanchilton

also we recommend that embedded expressions always have string quotes around them. yes the json parser is lenient but it causes trouble like this. the design of embedded expressions is so that JSON remains well-formed: https://github.com/karatelabs/karate#embedded-expressions

ignore my above comment, there indeed seems to be a regression in latest versions. @LanDinh do note that we spend a LOT of time creating RC versions, so if you try those earlier and provide feedback, that would save all of us a lot of trouble

is fixed in develop no ETA for release
