val context : Context = mock()
val handler = MicronautLambdaContainerHandler()
val output = ByteArrayOutputStream()
// inputJson is the above string AWS Http API v2
handler.proxyStream(inputJson.toString().byteInputStream(), output, context)
I am getting the bellow error. Is Micronaut unable to parse latest AWS Http Api proxy call to lambda?
com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of java.lang.String out of START_OBJECT token
