I am writing a powershell script to copy the sharepoint online list items from one sharepoint online list to another while that list consist of 77 fields. I am getting below error. While the same copy code works for list having lesser fields. Do we face problems when we have more number of fields in sharepoint online powershell. There is no attachment or document in list.

Exception calling "ExecuteQuery" with "0" argument(s): "The request message is too big. The server does not allow messages larger than 2097152 bytes."
