Performing a JsonPath replacement in groovy
The following code works in a groovy step, but if you notice, I am replacing an element by hard position referencing i.e. references[0]: json.cEntity.references[0].userValue = "newID_ONE###" ...
You can try the below
json.cEntity.references.find{it.name == 'ID_ONE'}.userValue = "newID_ONE###"
