Unhandled Exception: PlatformException(functionsError, Cloud function failed with exception., {code: INTERNAL, details: null, message: INTERNAL}) #1

First of all, thank you for this cloud function CRUD example. The CloudFunctions.instance.call has changed so I changed your implementation of the following code

CloudFunctions.instance.call(
    functionName: "addUser",
    parameters: {
      "name": _nameTextController.text,
      "email": _emailTextController.text
  });

to this 

final HttpsCallable callable = CloudFunctions.instance
    .getHttpsCallable(functionName: "addUser");
await callable
    .call({
      "name": _nameTextController.text,
      "email": _emailTextController.text
    })
    .then((value) => print(value.data))
    .catchError((onError) => print(onError.toString()))
    .whenComplete(() => print('finally complete'));

With this, the new user is added to firestore as expected, but I am having this Platform exception. What can be the cause?

Thanks for pointing out the implementation change🙂. Instead of chaining with then() and catchError(), could you try try ... catch ?

Referencing an example from cloud_functions package :

try {
  final HttpsCallableResult result = await callable.call(
    <String, dynamic>{
      'message': 'hello world!',
      'count': _responseCount,
     },
    );
    print(result.data);
   });
  } on CloudFunctionsException catch (e) {
    print('caught firebase functions exception');
    print(e.code);
    print(e.message);
    print(e.details);
  } catch (e) {
    print('caught generic exception');
    print(e);
}
