I'm trying to use new JSON support but without luck. In Variable Extractor there is no XPath field open nor any changes happened between 4.0 and 4.1.2. Are there any prerequsites to get it working?
Since NeoLoad 4.1.2, the Xpath method is now enabled when creating a variable extractor on JSON response with XML conversion enabled. Plus also related to Json, if needed you can decide to disable the conversion of the Json requests/responses to an XML format.
This is done under menu "Edit-->Preferences-->Project settings-->Runtime parameters"
