Service failed server unhealthy

Hi!
I saw there were others questions about this topic, but none like my example.
I’m trying to deploy a spring java web app.
It seems go everything ok with a deploy live msg, but then I get server unhealthy several times.
When I go to the link, it seems I get the normal Whitelabel error page, and going to a safe path it show the empty content of the table.
I don´t know what should I do. If my service is ok to use by my front end or not.
Thank you!
Miguel.

Hi there,

The best place to start would be the service logs, this looks like a code issue returning an empty array.
