I am using PowerShell script listed here: http://www.sharepointdiary.com/2016/11/sharepoint-online-import-terms-to-termset-using-powershell.html to update managed metadata terms but for some reason its throwing an error. It was working fine when I tested on my test tenant but in production (end client, different tenant), Its not working. Below is the error message:
"Error Importing Term Store Data! Exception calling ExecuteQuery with 0 arguement(s): For security reasons DTD is prohibited in this XML document. To enable DTD processing set the DtdProcessing property on XmlReadersettings to parse and pass the settings into XmlReader.Create method."
Can someone please help me why I am seeing this error and what is the solution, thanks in advance. P.S: I am using the exact same Powershell script that is in the article link I mentioned above, with the changes being, tenant url, CSvheader etc.
