Okhttp 为什么在尝试匿名登录IBM AppID时会发生崩溃？

每当我尝试使用Android匿名登录时

appId = AppID.getInstance();
appId.initialize(this,tenantId, region);
appId.signinAnonymously(this, new AuthorizationListener() {
          @Override
          public void onAuthorizationFailure(AuthorizationException exception) {
          }
          @Override
          public void onAuthorizationSuccess(AccessToken accessToken, IdentityToken identityToken, RefreshToken refreshToken) {
          }
          @Override
          public void onAuthorizationCanceled() {
          }
      });

我在启动时遇到此错误：

FATAL EXCEPTION: OkHttp Dispatcher
    Process: com.watizit, PID: 9411
    java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.String.equals(java.lang.Object)' on a null object reference

        at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:641)
        at java.lang.Thread.run(Thread.java:929)

当我移除这个同名的块时，它就不再崩溃了。 我怀疑回调+okhttp有问题，但我不知道具体是什么问题。 你知道怎么解决吗？多谢各位

以下是如何定义我的依赖项（默认）：

}

我只加了一行： 实现'com.github.ibmcloudsecurity:appid clientsdk android:6.+'

dependencies {
implementation 'com.github.ibm-cloud-security:appid-clientsdk-android:6.+'
implementation fileTree(dir: "libs", include: ["*.jar"])
//noinspection GradleDynamicVersion
implementation "com.facebook.react:react-native:+"  // From node_modules


debugImplementation("com.facebook.flipper:flipper:${FLIPPER_VERSION}") {
  exclude group:'com.facebook.fbjni'
}


debugImplementation("com.facebook.flipper:flipper-network-plugin:${FLIPPER_VERSION}") {
    exclude group:'com.facebook.flipper'
    exclude group:'com.squareup.okhttp3', module:'okhttp'
}

debugImplementation("com.facebook.flipper:flipper-fresco-plugin:${FLIPPER_VERSION}") {
    exclude group:'com.facebook.flipper'
}

if (enableHermes) {
    def hermesPath = "../../node_modules/hermes-engine/android/";
    debugImplementation files(hermesPath + "hermes-debug.aar")
    releaseImplementation files(hermesPath + "hermes-release.aar")
} else {
    implementation jscFlavor
}
