I attempted to use GlideAjax with RESTMessageV2 to call an external API from a UI Action, but I'm unable to receive the response on the client side.
As a test, I tried returning a random string before the execute() method, and I was able to receive it on the client side. However, when I returned a random string after the execute() method, I couldn't receive it on the client side.
How should I address this issue?
