Shortcut suggestion from In-App Promo SDK is blank and produces an error

Question

I'm trying to use the "In-App Promo SDK" to suggest a shortcut to the user using createShortcutSuggestionIntent.

I have submitted my signed app bundle to the google play console under internal testing.

I have created a preview using the App Actions Test Tool. I can successfully use the App Actions Test Tool to run an app action with actions.intent.OPEN_APP_FEATURE, and it opens my app at the desired activity. If I manually add the shortcut to assistant it works as desired and I can open specific features in my app using voice commands. createShortcutSettingsIntent works as expected.

The only problem is the in-app shortcut suggestion not working.

val shortcutsClient = AssistantShortcutSuggestionsClient.builder()
    .setContext(this@MainActivity)
    .setVerifyIntents(true)
    .build()

val appShortcutIntent = AppShortcutIntent.builder()
    .setIntentName("actions.intent.OPEN_APP_FEATURE")
    .setPackageName("com.mypackage")
    .setIntentParamName("feature")
    .setIntentParamValue("test")
    .build()

if (shortcutsClient.lookupShortcut(appShortcutIntent).await().isShortcutPresent) {
    return
}

val orderShortcut = AppShortcutSuggestion.builder()
    .setAppShortcutIntent(appShortcutIntent)
    .setCommand("my shortcut phrase")
    .build()

val intent = shortcutsClient.createShortcutSuggestionIntent(orderShortcut).await()
application.startActivity(intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK))

The shortcut suggestion activity opens for a brief moment but doesn't render any text. Here is the error:
