java.lang.IllegalArgumentException: Invalid notification (no valid small icon)

[jamesholcomb]

Any ideas why the default ic_launcher.png icon is not resolving? The file exists in the /res/mipmap-* folders (/src/debug and src/main). When receiving notifications in the background, the ic_launcher icon displays correctly in the status bar and on the notification bubble.

buildscript {
    ext {
        googlePlayServicesVersion = "16.+"
        buildToolsVersion = "29.0.2"
        minSdkVersion = 16
        compileSdkVersion = 29
        targetSdkVersion = 29
        supportLibVersion = "28.0.0"
        androidMapsUtilsVersion = "0.5+"
    }
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath("com.android.tools.build:gradle:3.5.3")
        classpath("com.google.gms:google-services:4.3.3")
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

PushNotificationAndroid.notify({
      title: "title",
      body: "body",
      click_action: "fcm.ACTION.HELLO"
    });
