AppSync codegen model "S3ObjectInput" methods override error

[cjae]

Describe the bug
when I try to build my project I always ran into the following error which does appear for every list item:

error: S3ObjectInput is not abstract and does not override abstract method mimeType() in S3InputObjectInterface

To Reproduce
Steps to reproduce the behaviour:

1. Update appsync android dependency to 3.3.2.
2. Run clean Gradle build.
3. "S3ObjectInput" model is generated but is not abstract and does not override the methods declared in "S3InputObjectInterface" which it implements.

Expected behavior
S3ObjectInput should implement localUri() and mimeType() methods of "S3InputObjectInterface

Environment(please complete the following information):

• AppSync SDK Version: 3.3.2
