UFT 23.4 Http Request json escape characters

Hi,

we're facing a problem with API Test that use an HTTP Request. The test has been created using 2021R1 version and use a JSON format. The json is formatted in the correct way and if the test run using 2021R1 the request correctly add the escape character for double quote. Instead using 23.4 the escape character does not add in the request and it fails.

INPUT JSON is something like this:

{"param1":"value1","param2":"value2"}

using UFT 2021R1 the request is correctly managed and I can see in the report:

{\"param1\":\"value1\",\"param2\":\"value2\"}

using UFT 23.4 the request has send in plain text and fails:

{"param1":"value1","param2":"value2"}

Do you know if there is some option in UFT to set?

thank you,

Massimo.
