Dear developers,

While using DHIS2 (version-2.29), sometimes, we are facing following error
on the browser.

Unable to get schemas from the DHIS2 API.

While tailing the dhis.log file, we found following message:-

WARN  2018-10-25 09:02:02,525 Failed to invoke @ExceptionHandler method:

Any idea why this is happening frequently?

Thanks & Regards,
