XML error in Copy activity

Question

Hi,
I am trying to run a copy activity with the source being blob (result of hive query) and destination being Azure SQL. Following is the error which I am getting:
HDIS copy activity encountered an unknown server error: Code: 0 ; Message: 'Type=System.InvalidOperationException,Message=There was an error generating the XML document.,Source=System.Xml,''Type=System.ArgumentException,Message='',
hexadecimal value 0x01, is an invalid character.,Source=System.Xml,'.
Here is the activity JSON

Finally was able to figure out the issue.
The columndelimiter for AzureTableDestBlobTable was missing. As we are using avro format had to specify ^A as the columndelimiter.
   "name":"AzureTableDestBlobTable",
   "properties":{  
 "location":{  
        "type":"AzureBlobLocation",
        "folderPath": "<container>/output/courseactivity/",
"format":
            "type": "TextFormat",
             "columnDelimiter": "\u0001"
        "linkedServiceName":"AvroBlobStore"
      "availability":
        "frequency":"Day",
        "interval":1
