Gson ignore too many properties in nested object

Issue

I have a JSON with this structure:

{
  "firstProperty": true,
  "thisIsAString": "hi",
  "myList": [
    {"myBool": true},
    {"myBool": false, "otherfield": true}
  ]
}

The myList is a List<MyClass> in the target class. This MyClass only has the myBool field which causes the first element of the array to properly deserialize but unfortunately deserializing the second element causes it to fail with the error message Unknown property 'myBool' for class my.package.MyClass at JSON path $.otherfield.

Is there any way to just ignore fields in the JSON that don't exist in the target class of the deserialization? Maybe it is because of nested objects?

I already tried to add a custom type adapter like seen here but it didn't even call the method (the target class is a record which is why i have to use the third party library com.github.Marcono1234:gson-record-type-adapter-factory to deserialize it)

Solution

I found the issue, the third party library I use to deserialize into records has a TypeAdapterFactory which has a option to ignore unknown properties which is set to false per default.

Turning this option on produces the expected output.
