The PowerServer log level is changed from "Debug" to "Warning" by default. So you will get faster responses but fewer log information in the Web API console.
If you want to view detailed logs (for example, the activities of DataWindow operations) in the Web API console, you can change the PowerServer log level to "Debug" or "Trace" in the PowerServer solution > ServerAPIs project > Logging > Logging.Development.json file, for example,
"PowerServer": "Debug"
