android - Error while uploading symbols to Firebase Crashlytics

Question

I set up a firebase project with crashalytics and I can see Java and NDK crashes on the Dashboard. I am trying to upload symbols as per https://firebase.google.com/docs/crashlytics/ndk-reports#upload_native_symbols. I also tried following blogs like https://medium.com/@aungkyawmyint_26195/setting-up-ndk-crashlytics-android-11ad775676f7, but have been unsuccessful so far.

Here is my environment

Android Studio 3.5
Build #AI-191.8026.42.35.5791312, built on August 8, 2019
JRE: 1.8.0_202-release-1483-b49-5587405 x86_64
JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o
macOS 10.14.6

implementation 'com.google.firebase:firebase-analytics:17.2.0'
implementation 'com.crashlytics.sdk.android:crashlytics:2.10.1'
implementation 'com.crashlytics.sdk.android:crashlytics-ndk:2.1.0'

When I run

./gradlew crashlyticsUploadSymbolsDebug --stacktrace

with below in my app/build.gradle

crashlytics {
    enableNdk true
    androidNdkOut 'build/intermediates/cmake/debug/obj'
    androidNdkLibsOut 'build/intermediates/cmake/release/obj'
    manifestPath 'src/main/AndroidManifest.xml'
}

I get the following error
