Took me hours to finally figure this out and Google doesn't help in this case.\r\n\r\n","author":{"url":"https://github.com/dfrommi","@type":"Person","name":"dfrommi"},"datePublished":"2019-06-29T09:31:34.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/80/HAP-Java/issues/80"}
