Using the ExtractVariables policy, i retrieved the value of a JSON element which is a Boolean and stored it in a variable. When I checked by triggering the API, the value was getting passed to the variable, later after the extract variables policy I used the XSLT transform policy and passed that variable as a parameter ref and used it in the XSL. But the output of the XSL had a blank value for the tag which had it's mapping from this variable. Later in my extract variables policy, I pointed to fetch the different JSON element which had a Non-Boolean value. The output of the XSL had the corresponding tag value with that Non-Boolean value. kindly help.
