Unable to add field to REST API

[twmobius]

So I've started with a ZF3 skeleton APP, and added Apigility as in the recipe (https://apigility.org/documentation/recipes/apigility-in-an-existing-zf2-application).

I've added via the composer zf-apigility 1.3.0 and zf-apigility-admin 1.5.10. I've added ApigilityProviderInterface in the Module.php and went to the admin-ui. I've added a new REST service in the module and tried to add a field. And there I'm getting errors on the console:

Duplicates in a repeater are not allowed. Use 'track by' expression to specify unique keys.

Looking into the network on the input-filter request I am getting multiple warnings and notices:

Warning: Illegal offset type in vendor/zfcampus/zf-configuration/src/ConfigResource.php on line 113
Notice: Undefined index: zf-content-validation in vendor/zfcampus/zf-apigility-admin/src/Model/InputFilterModel.php on line 141
Warning: Illegal offset type in vendor/zfcampus/zf-configuration/src/ConfigResource.php on line 113
Notice: Undefined index: input_filter_specs in /endor/zfcampus/zf-apigility-admin/src/Model/InputFilterModel.php on line 159

Eventually ending with a Internal Server Error with the message "Passed variable is not an array or object"

Searching through the generated module.config.php I can see that no 'input_filter_specs' => array() or 'zf-content-validation' => array() have been created. I tried adding the manually but I couldn't make it to work.

@twmobius Just guessing, but it seems for me that you are affected by #378
Please try set zfcampus/zf-configuration to <=1.3 in your composer and run composer update.
You can check before if you have installed version 1.3.1 of zf-configuration (composer show).

@webimpress You are right! I was using 1.3.1. Downgrading to 1.3.0 resolved the issue. Thank you very much!!
