Enhanced client bug when dealing with kotlin nullable booleans whose names start with "is"

[StormeHawke]

Describe the bug

When using a nullable boolean property in kotlin which is prefixed by is, the property is ignored by the enhanced client when building the schema, even if you add the @DynamoDbAttribute annotation to override the name.

Expected Behavior

I recognize that I need to override the db field name due to the "is" prefix, but I expect a nullable boolean property to work just as well as a non-nullable rather than being ignored. I have another field in my same bean that works fine:

    @get:DynamoDbAttribute("isDeleted")
    var isDeleted: Boolean = false,

This property outputs logs like
some.package.model.SomeModel - Property deleted read method: public final boolean some.package.model.SomeModel.isDeleted() ||main|s.a.a.e.d.beans
some.package.model.SomeModel - Property deleted write method: public final some.package.model.SomeModel.setDeleted(boolean) ||main|s.a.a.e.d.beans

Current Behavior

With the debug logging turned on, you get a message like this in the log:

some.package.model.SomeModel - Ignoring bean property foo because it has no read (get/is) method. ||main|s.a.a.e.d.beans

Note: If you remove the ? and instead define the field as
var isFoo: Boolean = false
then the property works as expected.

Reproduction Steps

Here's an example bean that should replicate the issue

@DynamoDbBean
data class SomeModel(
    @get:DynamoDbPartitionKey
    var id: String

    @get:DynamoDbAttribute("isFoo")
    var isFoo: Boolean? = false
)

Possible Solution

I'm not sure what a fix might be, but I did figure out a workaround by delegating the property as follows, and marking my "real" property with @DynamoDbIgnore. Note the property is still nullable, but by getting rid of the "is" prefix the property plays nice with the sdk

    @get:DynamoDbAttribute("isFoo")
    var fooDelegate: Boolean?
        get() = isFoo
        set(ooo) { this.isFoo = ooo }
