Hello guys.

I’m not able to get a value because the property name has special characters

example:  
“Result”:{“@type”:“Result”}

If I do

WSBuiltInKeywords.verifyElementPropertyValue(response, ‘Result.@type’, ‘Something’)

or

WS.getElementPropertyValue(response,‘Result.@type’)

ERROR c.k.k.core.keyword.internal.KeywordMain - ? Unable to verify element property value (Root cause: groovy.lang.MissingFieldException: No such field: type for class: groovy.json.internal.LazyMap

ERROR c.k.k.core.main.WSVerificationExecutor - ? Verification FAILED.  
Reason:  
com.kms.katalon.core.exception.StepFailedException: Unable to verify element property value (Root cause: groovy.lang.MissingFieldException: No such field: type for class: groovy.json.internal.LazyMap

Open to ideas hehe, thanks!

This is not a valid JSON. It would never be properly processed by any JSON Parser.

I guess you wanted

```auto
{"Result":{"@type":"Result"}}

```

You can find the source code of `WS.verifyElementPropertyValue` keyword at

> <https://github.com/katalon-studio/katalon-studio-testing-framework/blob/master/Include/scripts/groovy/com/kms/katalon/core/webservice/keyword/builtin/VerifyElementPropertyValueKeyword.groovy>

You should read the source to investigate whatever problem about the keyword.

I could reproduce the problem with the following code:

```auto
import com.kms.katalon.core.webservice.helper.WebServiceCommonHelper as WSCH

String content = '''{"Result":{"@type":"Value"}}'''

Object obj = WSCH.parseAndGetPropertyValueForJson('Result.@type', content)
println obj

```

Console output:

The following code worked:

```auto

String content = '''{"Result":{"@type":"Value"}}'''

Object obj = WSCH.parseAndGetPropertyValueForJson('Result."@type"', content)
println obj

```

Output:

One more exercise:

```auto
import com.kms.katalon.core.webservice.helper.WebServiceCommonHelper as WSCH

String content = '''{"Result":{"@type":"Value"}}'''

Object obj = WSCH.parseAndGetPropertyValueForJson('Result["@type"]', content)
println "obj=" + obj

```

This worked fine:

```auto
2023-09-10 13:17:08.508 INFO c.k.katalon.core.main.TestCaseExecutor - --------------------
2023-09-10 13:17:08.511 INFO c.k.katalon.core.main.TestCaseExecutor - START Test Cases/testGPath

Test Cases/testGPath
PASSED
2023-09-10 13:17:09.154 INFO c.k.katalon.core.main.TestCaseExecutor - END Test Cases/testGPath

```

This proves that the expression `'Result["@type"]'` is evaluated valid.

The expression `'Result["@type"]'` looks familiar to me. It is just the same as a code in JavaScript that gets access to a property of an object.

On the other hand, the expression `'Result."@type"'` looks puzzling to me. I have never seen this syntax in any other places.
