I am trying to create a form on the backend in my Magento 2.1 module using ui_component. However, when I am trying to access the page of the module it throws error 500.
Here is the outcome of apache error logs:
[Fri May 26 14:03:15.423368 2017] [:error] [pid 13863] [client
xxx] PHP Fatal error: Method Magento\Ui\TemplateEngine\Xhtml\Result::__toString() must not
throw an exception, caught Error: Call to a member function
addFieldToFilter() on null in
/data/sites/project_name/vendor/magento/module-ui/Component/Wrapper/UiComponent.php
on line 0
Here is the module's structure:
