are you sure nothing is coming out? The HTTP connectivity is likely suppressed by Gradle, though there should still be something from AWS code.

This will help re-enable the HTTP logging:

public fun enableHttpClientHeaderLogging() {
    val loggerFactory = LoggerFactory.getILoggerFactory() as OutputEventListenerBackedLoggerContext
    val loggersField: Field = OutputEventListenerBackedLoggerContext::class.java.declaredFields.first { it.name == "loggers" }
    loggersField.isAccessible = true
    val loggers = loggersField.get(loggerFactory) as ConcurrentHashMap<*, *>
    loggers.remove("org.apache.http.headers")
    println("Enabled HTTP client header logging; you may need to restart the daemon (./gradlew daemon --stop)")
}
