When using a JSON Fact, what is the best way to retrieve the modified then properties

[mbdiego]

I am trying to loop through all the matching rules and extract the modified property.

Invoking the following retrieves the original data but not the modified value in the then condition
result := dataCtx.Get("MF").Value().Interface().(map[string]any)

ruleEntries, err := eng.FetchMatchingRules(dataCtx, knowledgeBase)
if err != nil {
    panic(err)
}

for _, r := range ruleEntries {
fmt.Println(r.ThenScope)
}

Simple Rule for this example is as follows:

rule CheckValues "Check the default values" salience 10 {
    when
        MF.First_name == "John" && MF.Last_name == "Doe"
    then
        MF["Result"]=true;
        Retract("CheckValues");
}
