It seems there was an error on the server

Hi, 

Im trying to generate a document in word using the Adobe Document Generation plugin, using the json data as below. When I click on generated document I get the error as in screenshot below. I Validated the json and didn't find any issues.

Any ideas

[  
  {
        "OwnerID": "L001",
		"Properties": [
				{
					"PropertyID": "P001",
					"Property Address": "12 St LA",
					"Rent": "300",
					"Bedroom": "2"
				},
				{
					"PropertyID": "P002",
					"Property Address": "3 St SA",
					"Rent": "450",
					"Bedroom": "3"
				}
			]
	},
    {
        "OwnerID": "L002",
        "Properties": [
				{
					"PropertyID": "P003",
					"Property Address": "4 St SA",
					"Rent": "500",
					"Bedroom": "4"
				
				}
			]
	},
    {
        "OwnerID": "L003",
        "Properties": [
				{
					"PropertyID": "P004",
					"Property Address": "20 St LA",
					"Rent": "400",
