And found below error in DSSError.log
JSON string length is xxxxxxx, greater than xxxxxxx and can't be handled by NEE.
CAUSE:By default, the JSON string limitation is 100M in Intelligence Server, so if the dashboard hit the limitation, this error would show up.
ACTION:This issue is fixed in Strategy 10.8. After upgrading to 10.8, take below actions.
- Go to <INSTALL_PATH>/IntelligenceServer/PDFExportService, open application.properties file and modify the MaxMemoryUsageInMbytes to a number larger than 100.
- Restart Export Engine Service.
