ERROR: In project 'app' a resolved Google Play services library dependency

Question

I got a problem as follows, I didn't know how to fix it, please help me. Thank you.

In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[1.13.1]", but isn't being resolved to that version. Behavior exhibited by the library will be unknown.

Dependency failing: io.grpc:grpc-auth:1.13.1 -> io.grpc:grpc-core@[1.13.1], 
but grpc-core version was 1.15.1.

The following dependencies are project dependencies that are direct or have 
transitive dependencies that lead to the artifact with the issue.

-- Project 'app' depends onto io.grpc:grpc-netty-shaded@1.13.1
-- Project 'app' depends onto com.google.api:gax-grpc@1.32.0
-- Project 'app' depends onto io.grpc:grpc-core@1.15.1
-- Project 'app' depends onto io.grpc:grpc-protobuf@1.13.1
-- Project 'app' depends onto io.grpc:grpc-protobuf-lite@1.13.1
-- Project 'app' depends onto com.google.cloud:google-cloud-core-grpc@1.49.0
-- Project 'app' depends onto io.grpc:grpc-okhttp@1.15.1
-- Project 'app' depends onto com.google.cloud:google-cloud- dialogflow@0.67.0-alpha
-- Project 'app' depends onto io.grpc:grpc-auth@1.13.1
-- Project 'app' depends onto io.grpc:grpc-stub@1.13.1

For extended debugging info execute Gradle from the command line with 
./gradlew --info :app:assembleDebug to see the dependency paths to the 
artifact. This error message came from the google-services Gradle plugin, 
report issues at https://github.com/google/play-services-plugins and disable 
by adding "googleServices { disableVersionCheck = false }" to your 
build.gradle file.

Please help me about this, it made me crazy!

Change io.grpc version to '1.13.1' as mentioned below in app's build.gradle.

// Java v2
    implementation 'com.google.cloud:google-cloud-dialogflow:0.67.0-alpha'
    implementation 'io.grpc:grpc-okhttp:1.13.1'
