Can't find a codec for CodecCacheKey{clazz=class domain.Product, types=null}.

MongoDB

I'm getting this CodefCacheKey error when Test Mode. It worked on 3.9 version i'm currently running v4.
However if I run testFunctionRequestHandler it works and when I run testApi I get the error.
This being said, it also works on AWS lambda native but doesn't work on AWS shadowJar.

Please help.

@Inject
lateinit var catalogController: Controller

@Test
fun testFunctionRequestHandler() {
    val product = catalogController.getProduct("64afc8ea21c2f173458c93a9")
    assertNotNull(product)
}

@Test
fun testApi() {
    val handler = ApiGatewayProxyRequestEventFunction()
    val request = APIGatewayProxyRequestEvent()
    request.httpMethod = "GET"
    request.path = "/catalog/product/64afc8ea21c2f173458c93a9"
    val response = handler.handleRequest(request, lambdaContext)
    assertEquals(200, response.statusCode)
    handler.applicationContext.close()
}

If you put your entities outside of the application package, you need to specify it in the mongo configuration:

mongodb:
  package-names:
    xyz
