Take a look at tracing-palette-bug.mp4. I am assuming that for the tracingColorTypeValue attribute, the TracingColorType.TRACINGFULLCOLOR and TracingColorType.TRACINGLIMITEDCOLOR keys work in reverse. And we can't set the palette color limits correctly.

Look at tracing-preset-bug.mp4. The script should load the default settings for tracing. But what we see, again like in the previous video, we have problems with the number of colors for the Palette. This could be tolerated when in CC 2019 the result after the script was like manually selecting a preset, but in CC 2023 and this is broken and users can't trust the automation of tracing.

I think the Adobe team needs to do a full SDK revision for ExtendScript on tracing methods and attributes.
