StaleObjectException

[janaltenhof]

Hi, when I want to run the Baseline Profile Generator in step 7 of the codelab I'm getting this error.
I don't know what to do? Can you help me?

com.google.baselineprofile.BaselineProfileGenerator > generate[pixel6Api31] FAILED 
	androidx.test.uiautomator.StaleObjectException
		at androidx.test.uiautomator.UiObject2.getAccessibilityNodeInfo(UiObject2.java:647)

I could not reproduce this locally. Sometimes this happens when the screen turns off during benchmarking. Make sure the display time out is set long enough.

Please @keyboardsurfer, reactivate this issue, since I'm getting this error over the following run configuration.
Android Studio Iguana | 2023.2.1 Canary 7
AGP = 8.0.0
androidx-baselineprofile = "1.2.0-alpha13"
profileinstaller = "1.3.0"

running task
./gradlew :app:generateReleaseBaselineProfile -Pandroid.testInstrumentationRunnerArguments.androidx.benchmark.enabledRules=BaselineProfile --info

Update @janaltenhof:
By updating the following configuration I made it work.

    testOptions.managedDevices.devices {
        create<ManagedVirtualDevice>("pixel6Api30") {
            device = "Pixel 6"
            apiLevel = 30 // CHANGED FROM 31 TO 30, (32 DIDN'T WORK)
            systemImageSource = "aosp"
        }
    }

Additional note, the following configuration, testing on a physical device using API 34 (Android 14), didn't work.
baselineProfile {
// managedDevices += "pixel6Api30"
useConnectedDevices = true
}

We're working on addressing this within the Macrobenchmark library itself.
In the meantime we recommend running the tests again in case they fail with a StaleObjectException.
