Hi Patrick, Thank you so much for taking time to write answer. Unfortunately it is not working I have screenshots for your review. I have been struggling since last week please help.
What happens when you click on the "update" button?
Your screen shot is only showing that the validation failed. The user validation is run in debug mode which means that any response content (even binary) will be displayed.
We have exactly the same issue with JSON requests. The recording is not stored in NeoLoad. Also the update recording does not work either. Luckily when playing back (Check) the user path the responses were displayed and we could correlate and update the user path based on this. Not perfect but at least a way to unblock the issue.
