Failed to parameterize scripts

Phenomena: After the scripts are recorded, the plain text cannot be found in all web_custom_request as shown below:

web_custom_request("appeon.weblibrary.AXDispatcher3",

Solution: Before running the scenario, make sure that you have selected Test Mode in the Run Mode settings of AEM and that you have set the log mode to Standard. Then the plain text ("--------------------appeon data\r\n" "Name = Connect\r\n" "session_id = -1476559241\r\n" "--------------------appeon data\r\n" "P" "\\x00\\x00\\x00" ) will appear as shown below.
