Alexa Smart Home response problem using haaska

I’m not sure if this is a HA or hasska issue, but
I’m successfully using haaska to integrate Alexa into HA, apart from one annoying issue. I’ve only tested the Alexa integration with EspHome devices, which work fine, but if I power down a ESP device to make it unreachable, Alexa still acknowledges with ‘OK’ after a voice request! HA shows the ESP device as offline too. I have seen in the HA log that the endpointhealth response is ‘unreachable’ but she still says ok! I would like her to return that there is a problem instead.

Using the Alexa app, it shows that the device actually is unreachable, but voice requests acknowledge ‘OK’.

Has anyone else experienced this problem, or have any solutions?!?
Kind regards
