Issues Generating a Report - Bad Request

Problem:

An unexpected error occurs when generating a report. The following error message can be found in the browser console.

Error running job. GR001.400: Bad Request

Cause:

For WebMaps with many layers and the use of CIM symbols, requests during reporting can become very large and exceed defined limits in the IIS configuration.

Solution:

To resolve the issue, two adjustments must be made in the web.config of the Reporting Service.
