During recording time i clicked "Buy" button and corresponding scenario has been added while trying to play back i received error saying "The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable". Buy button available in the application. Kindly guide me how to over come this issue?
I was not able to see the content of the file you attached but your issue seems to be related to dynamic parameters that are not handled.
You should check the requests parameters to see if you do not have any id's that should be correlated.
You can record twice the same transactions and compare the parameters to identify them. If you see id's that have different value on the two recordings for the same request then it means that they are dynamics.
You should use variable extractor to handle them. Please look at the NeoLoad documentation to know how to do it. You can check the tutorial here too.
