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')]"
}
