Troubleshooting tips

Consider the following tips when you troubleshoot the Case Exchange integration:

Incorrect configuration of the Base URL, User Name, and Password fields in the General tab usually causes authentication failure. In this scenario, 401 errors are recorded in the log file.
You can enable the error-handling feature when you configure the integration instance. SMIS can automatically create a new Incident record if a Case Exchange task fails. The Description field of this Incident record contains the details of the failed task record. For more information about the error-handling feature, see Error handling.
Due to a known limitation, the error message in the SMIS task log may be insufficient to identify the root cause of a failed task. For more information about this known limitation and the workaround, see Insufficient message for a failed Case Exchange task.
