’workload-webgpu-trace.json‘ format does not include the prefixes CPU::ORT or GPU::ORT.

[137591]

The command node main.js --timestamp-format day --tasks workload --workload-url http://localhost:8000/src/minist-demo.html --enable-trace --enable-trace is used to record performance data for my application.’ minist-demo.html‘ is an application workload for ONNX Runtime. However, in the generated workload-webgpu-trace.json format, there are no prefixes CPU::ORT or GPU::ORT, which causes the parseTrace function to fail to process it into a specific timelineJson format. I have already inserted ’window.ort.env.trace = true‘ in my program，Could you please clarify if I made a mistake in which step?
Here is one line from the workload-webgpu-trace.json that I generated.
