Description

If you are attempting to create or update a storage plugin and for whatever reason an error occurs, the only error message that is displayed in the GUI is 

Please retry: Error (unable to parse JSON)

This is unhelpful to the user as the user may have entered in valid JSON, but specified an invalid option. The error gives no indication as to what actually went wrong and how to fix.

See example below:

In this example, the cause of the error is the final option isMysql: false, which does not exist as a configuration option for the JDBC plugin.
