[Flutter] `ClassNotFoundException: boolean` on app start #997

Closed fjnoyp closed 3 years ago

fjnoyp commented 3 years ago

If you save a model with a boolean field, when you close and reopen the app and perform a query, the following error is shown several times. The app is still functional.

W/amplify:aws-datastore( 4745): java.lang.RuntimeException: DataStoreException{message=Error in querying the model., cause=com.google.gson.JsonSyntaxException: java.io.IOException: java.lang.ClassNotFoundException: boolean, recoverySuggestion=See attached exception for details.}

Our Dart save code uses the following values on the ModelField:

targetType javaClassForValue value type in Kotlin
Boolean Boolean::class.java boolean ?
jamesonwilliams commented 3 years ago

@fjnoyp Can you please include a code snippet to repro this, including the data you're passing to the Android library, the Kotlin ModelSchema you're using? Also, logs / full stack trace.

fjnoyp commented 3 years ago

The logs are very repetitive, it keeps saying boolean cannot be found. Here's a snippet starting from the beginning:

This is our schema: 

enum TestEnum { 
  yes,
  no,
  maybe
}

type AllTypeModel @model { 
  id: ID!
  stringType: String!
  intType: Int!
  floatType: Float!
  boolType: Boolean!
  dateType: AWSDate!
  dateTimeType: AWSDateTime!
  timeType: AWSTime!
  timestampType: AWSTimestamp!
  enumType: TestEnum 
}
fjnoyp commented 3 years ago

This happens after saving the model. Even if we don't call any queries on app startup the logs shown above complaining about class not found boolean is still shown ...

@jamesonwilliams please let us know if you need anything else.

fjnoyp commented 3 years ago

This is the model that's saved (according to the logs from Amplify Android):

jamesonwilliams commented 3 years ago

Note to self: it looks like the ClassTypeAdapter is reading a lower-case boolean when it wants to read java.lang.Boolean. Todo: why?

com.amplifyframework.core.model.types.GsonJavaTypeAdapters$ClassTypeAdapterFactory$ClassTypeAdapter.read(GsonJavaTypeAdapters.java:106)

Note to self no. 2: the boolean value is saving correctly, and the app is not crashing. This is strange behavior that we should look into because it spams the logs, but as a lower priority. This might worry customers and increase the operational load.

jamesonwilliams commented 3 years ago

@fjnoyp In your ModelSchema dump, I see a mix of primitives and Number types:

Are you doing anything different for the java.lang.Integer, as compared to the double & boolean? I think if you can get those to show as java.lang.Boolean and java.lang.Double, this issue will go away.

fjnoyp commented 3 years ago

Hi @jamesonwilliams I assume "type" is in reference to the ModelField's "javaClassForValue" builder field.

javaClassForValue expects a java class type. Here are the different types of java types we pass. We're passing a "::class.java" for every single type so I'm not too sure what we should do to get the ModelSchema system to have boolean show up as java.lang.Boolean ...

        "string" -> String::class.java
        "int" -> Integer::class.java
        "double" -> Double::class.java
        "date" -> Temporal.Date::class.java
        "dateTime" -> Temporal.DateTime::class.java
        "time" -> Temporal.Time::class.java
        "timestamp" -> Temporal.Timestamp::class.java
        "bool" -> Boolean::class.java
        "enumeration" -> String::class.java
        "model" -> Model::class.java
        "collection" -> List::class.java

We consistently send a java class for each of the different types. My assumption for why the ModelSchema dump would show it differently is because "boolean" and "double" are primitive data types so they aren't technically classes right? While I think Java autoboxing and the requirements of Amplify Android ModelSchema use an actual java class type "java.lang.Integer" and "java.langString".

I believe our previous issue with integer before was because we were sending "java.lang.int" originally. (ie. we were giving Int::class.java instead of Integer::class.java)

Hi @jamesonwilliams I assume "type" is in reference to the ModelField's "javaClassForValue" builder field.

Ah yup, the toString() didn't get updated when we change the field name. You are correct that it should say javaClassForValue. #1006 fixes the label in the toString().

javaClassForValue expects a java class type. Here are the different types of java types we pass. We're passing a "::class.java" for every single type so I'm not too sure what we should do to get the ModelSchema system to have boolean show up as java.lang.Boolean ...

        "string" -> String::class.java
        "int" -> Integer::class.java
        "double" -> Double::class.java
        "date" -> Temporal.Date::class.java
        "dateTime" -> Temporal.DateTime::class.java
        "time" -> Temporal.Time::class.java
        "timestamp" -> Temporal.Timestamp::class.java
        "bool" -> Boolean::class.java
        "enumeration" -> String::class.java
        "model" -> Model::class.java
        "collection" -> List::class.java

This all looks good to me, too.

Totally.

Understood. Hm. Yea, I'm not sure why we're getting the primitive types here, in this case. In the worst case, I can just add some logic to deserialize the primitives, too. That wouldn't be the end of the world. I guess I'll do that.
