@KingRabbid , the issue is caused by `headerManager.clear()` in the preprocessor. Currently, `TestElement.clear()` clears **all** the data, including "system" properties like "test_class", "gui_class", "name", and so on. I believe it causes the failure. If you want to clear the headers instead, you might try `headerManager.getHeaders().clear()`. However, I would suggest to refrain from modifying the headers dynamically, and use variables instead. -- This is an automated message from the Apache Git Service.
