I am not sure what wrong with "2020-08-01-preview" version but its working fine with stable version. below is my partial arm template code that working.

I changed to 2014-04-01 api version.

  "comments": "If Elastic Pool Name is defined, then curent database will be added to elastic pool.",
  "type": "Microsoft.Sql/servers/databases",
  "apiVersion": "2014-04-01",
  "name": "[concat(parameters('sqlservername'),'/',variables('dbname'))]",
  "location": "[parameters('resourcelocation')]",
  "properties": {
    "collation": "[parameters('collation')]",
    "zoneRedundant": "[parameters('zoneRedundant')]",
    "elasticPoolName":"[if(not(empty(parameters('sqlElasticPoolName'))),parameters('sqlElasticPoolName'),'')]",
    "edition": "[parameters('skutier')]"
  }
