> 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
> {code:java}
> Please retry: Error (unable to parse JSON)
> {code}
> 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:
> !image-2020-01-26-16-47-46-398.png!
> 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.
