Troubleshooting Synchronization Task

When you create a synchronization task that contains an invalid configuration, the Secure Agent displays a NULL error message. The NULL error message files are saved in a specific location. For example, <Secure Agent installation directory>\apps\Data_Integration_Server\<latest version of connector>\ICS\main\tomcat\log.
The session log captures the log and exception details of a failed synchronization task. You require special permission to run the application in debug mode.
If you exceed the maximum path length of 2048 characters for POST and GET requests in the field mapping, the following error message appears:
Read operation failed
For more information about the maximum path length limitation for POST and GET requests, see https://support.microsoft.com/en-us/help/208427/maximum-url-length-is-2-083-characters-in-internet-explorer
