**Hello,  
i am trying to generate a simple polygon inside an entity from a set of coordinates and it does not render.  
The same coordinates generate some points which render quite fine.  
Here is the [Sandcastle Link](https://sandcastle.cesium.com/#c=jVVtb9owEP4rFl8WJGTyCgmFah1F3TTWVqxrNTVT5QYD1oIdOYaOVvz3XZwQSEqr5gOy7/zcPX7uzqyJRGtGn6hEA8TpExrSlK2W+FbbjE+R3g4FV4RxKj81T0Ie8jWg0ohyCqAcjfX2JHfBUlH5EAkhp4MXFHIEX0xUD5nY96yO7ZieZVsd3++4rZ1b8Mxt+p5rdwLfs+2u5zl2ULhDvq0FJ1KJKudhZppLkixYZBxywBC8VTUQtb+JNqWD+zzTS8nU6VpmJ/Bc33cc07FaJUevY4HL7pqO55q+E6Btq4YNLCcIfN81uwHc0d1jbfjMwPN8s+uCy3JeY7uuk2V2fNtxPM/091jLsT3LCuyO71rAALAh/1NeIxHxZi64VgYEIbASEmqWCMZV+kCkJJvB/eF5sF9LtmSKrelQxDGNFBMcRNXFxMnOl2IynRoHSl+/ATWamaozIZGBshQMMV7I23zZFTL71fkhUe67Zxmrnb3kD/6DymqTg2dSLCdkCuvUQImubLIrZxbhIyrgZJUujPJE86RK6i1htAqgngpVcZndl4iUael6e/at6pFIxCBLr7xRtsWT0XntWML+0fgne6aoZ5k134Ky+UJN6IxKyiO6D/a16oCw47Obb7ejh5urh4vJ1a/L832gbb7Mu3+bdwJMBlOb6jCNtM0oenOP3121d2zqsBJlqYzqpDZbWcKCQZa9eDd0bla0WE4k8+YrrEtR4aVb7yJPlxpVgWpVeU/536Px+OqudRRwWAPv+BGxUjG8h3dsqhYQ2n731PAYgS/js+H347AP13k4PvtxvS/y8Wg14zavfKmvnhZUk1gbS5FfoOP563ALRiWR0WKDem/M6Vk2bMZHJlJ3B8zVkkDHMBL3KlpdTEajy4xEQb5onWchljfioGkarUY/VZuYnuYsP7NlIqRCKxkbGLcVXSbwUtC0/biK/lKFozTNYP32DtSfsjVi00HYqP3vhQ0UxSRNwTNbxbo5wsZpvw3nK7BYwNPE51drKmOyyY4srNNxbsQY99uwfY1SQsSPRB5E/A8).

It looks like the polygon heirarchy you pass in to the polygon needs to be an instance of PolygonHierarchy, not just an array. [Here’s a fixed example](https://sandcastle.cesium.com/#c=jVVtb9owEP4rFl8aJBbyCgmFah1F7TS2VrRrNTVT5QYD1owdOYaVVfz3nRNCEtpuzQdk33N3vucen1ljidaU/CYSDRAnv9GQpHS1NG8zm3EUZ9uh4ApTTuRR8zjiEV9DVBoTTiAojzaz7XEOwVIR+RALIaeDZxRxBB/DqocsM/DtjuNavu3YnSDoeK0CFlzDVuB7TicMfMfp+r7rhDs44tuD5FgqUa95qE1ziZMFjY1qDSYkb9UNWJVMMlM6uM9Pet5X6nZtqxP6XhC4ruXarX2NfscGyOlaru9ZgRuibesgNrTdMAwCz+qGwNErYx34rND3A6vrAWS7L2O7nqtPdgPHdX3fCspY23V82w6dTuDZUAHERvznnkYi2GYueNYZaAiGlZCgWSIoV+kDlhJvBvdVf7BfSbqkiq7JUDBGYkUFh6ZmYppJgaUmnk6NSqev3gg1mrqrMyGRgfQRFFG+a2/zuRBS/2bnw0E5dk91VYWdZSUkWrSqFavcilXFuucKWOUWZCbXnEmxnOAprFMjT9hKCul1hvd0zExW6cLYezSP6wTeamLWMei0itSOePElIqVZm3tl9a26SywYtLC3Z6S35mR0duCW0CfCrukfgnrOAbQgdL5QEzIjkvCYlLku6gBkHZ/efL4dPdxcPpxPLr9/OysTbfNls6bCI2Hl0MNIAZfd/ajwrHD8jypaE61Ipf78jB466JsiTzAe10pSPjdo84DwDF4oiDlyrOQJpZD6Q0oknR29YLPN535bTEFGYfNvSgWd3msvjanEnpxRf52KIrNLUiP0qsI/RuPx5V1JrKKv7ZdmsVIM3uI7OlULSOG8QIavJf80Ph1+KV3ffUGG49OvV+Xt2GXYtmoTVOO2oERiGS82kLT2ZmSuFwVqvGf6dAf1DC0xdJVi1qtxOp+MRt8A5jt9d9rulJyxzY0wcn010Gg1+qnaMHKSB3yky0RIhVaSGabZVmSZwE0kaftxFf8iyozTVIf120VQf0rXiE4HUePgXzFqoJjhNAVktmKZZFHjpN8G/1oYE3Dt+fxyTSTDG+2ysE/GudE0zX4bti+jlBDsEctKxr8).
