My release configuration

  isMinifyEnabled = true
      isDebuggable = true
      signingConfig = signingConfigs.getByName(BuildTypes.RELEASE)

      val proguards = fileTree("proguard") {
        include("*.pro")
      }
      
      proguards.toList().forEach {
        println(it.nameWithoutExtension)
      }
      
      proguardFiles(
        getDefaultProguardFile("proguard-android-optimize.txt"),
        "proguard-rules.pro",
        *proguards.toList().toTypedArray()
      )

I have been trying to resolve a moshi issue . It does not happen when i run the debug variant.

And I have absolutely no clue how to unravel this mystery .
