Property is_array NOT applied on array of custom_classes

[jan-benda-hci]

Hi,
first of all - great plugin, thank you!

I've ran into an issue checking the items of an array of custom classes.

My plugin configuration looks like this:
{ "name": "request-firewall", "config": { "debug": true, "err_code": 422, "exact_match": { "/pcidss/InitiateAction": { "POST": { "content_type": "application/json", "body": { "ProcessorId": { "type": "string","max": "24","required": true,"match": "^[%w%s%.%-%:%(%);,=/]*$" }, "Credentials": { "type": "CredentialsObject","min": "1","required": true,"is_array": "1" } }, "custom_classes": { "CredentialsObject": { "Id": { "type": "string","min": "36","max": "36","required": true,"match": "^[%w%s%.%-%:%(%);,=/]*$" }, "Text": { "type": "string","max": "254","match": "^[%w%s%.%-%:%(%);,=/]*$" } } } } } } } }

When I validate the following object
{ "ProcessorId": "567", "Credentials": [ { "Id": "29c76e0b-8ede-4b60-8f30-56a18dcf6967", "Text": "0492192277" } ] }

The response is:
Unexpected parameter in body.Credentials.1

When I try to validate the same as object (not an array), it works.
{ "ProcessorId": "567", "Credentials": { "Id": "29c76e0b-8ede-4b60-8f30-56a18dcf6967", "Text": "0492192277" } }

Is the is_array property ignored for custom_classes?
