I have recorded one script, made all parameters dynamic. Script was working fine for around 1hr but after that I am getting Server Error in Application. Again, I have recorded the script, same error is coming after 1hr. Have attached the screenshot, please have a look and let me know how to resolve this issue.
There's clearly a dynamic parameter that you forgot to handle since the script is only valid for 1 hour. Since you have two different recordings i would suggest you to compare the same requests from both recordings in order to identify that dynamic value.
It could be a token used for authentification at the HTTP header level or a sessionid somewhere in the request parameters.
I have verified all the requests and all parameters are dynamic but still getting the same error.
It's difficult to help you more without seeing your user path and a checkvu export. You are probably missing a parameter value somewhere.
