"TypeError: expected string or buffer" when Validation Options are set in config file but not provided in the resource field

[Civity-NL]

Overview

As explained in the Documentation I set up a default value for the validation options in the configuration file.

I try to add a resource not providing any input in the resource field for validation options, and this leads to a Server error.

The Server error is "TypeError: expected string or buffer" generated from the following line of code.

So this should take into account the case where the value is null.

I've added this as a solution:

`

 if value:

      provided_options = json.loads(value)

      default_options.update(provided_options)

`

This should solve the issue. Should I submit a PR?
