The maximum size of the request and response HTTP header(csv header)specified in bytes. If not specified, this attribute is set to 4096 (4 KB).
As the object which you are trying to sync is having more then 300 fields.So header is more then 4KB that is the reason its throwing an error. To troubleshoot this error you need to increase the maxHttpHeaderSize.
Please change properties present in server.xml
change the HTTP/1.1 Connector entry and set the maxHttpHeaderSize to “65536” (64Kb in bytes) as shown below:
