Normally when NeoLoad performs a post and there is non static data it will present the post content as a form. In this case it is presented as text. For some reason we are getting response code 500 for this step.
The type of the request should not change between recording and runtime except if you manually change it. And it does not depend on the data within the POST request.
In other words, if it was POST request with form type it should remain the same during the runtime.
Do you have an example of the request sent during recording and runtime so i can review them?
