Enabling Dashboard Chart from admin causes exception in opening admin-dashboard.

[aniket-rokade]

Whenever I enable Dashboard Chart from admin->Store->configuration, admin dashboard page does not work. It gives exception.

I tried below things to resolve it but to no help:

1. Created Cron job as described in below dev doc:
   http://devdocs.magento.com/guides/v2.0/config-guide/cli/config-cli-subcommands-cron.html

2. Changed parameter group setting of my RDS instance to ignore super user access to database:
   by setting value of log_bin_trust_function_creators to 1.
   (This is because when I tried to change indexer-mode to 'schedule' from 'save' it gave me error for not having super user access.)
   **
   Exception details displayed instead of dashboard page:**

I'm having the same problem. Clean install is fine but after I went through the Magento Migration, this error started to appear. Disabling the chart helps.
