Problem

The gem is looking for the translation key parameters_not_allowed.detail (plural), but the key is correctly defined as parameter_not_allowed.detail (singular) in the code. Because of this mismatch, the translation is not found, and the default English message is shown.

Code with the Issue

Here’s the problematic code:

title: I18n.translate('jsonapi-resources.exceptions.parameters_not_allowed.detail',
                       default: "#{param} is not allowed.", param: param)

Expected Behavior

The code should look for the translation key parameter_not_allowed.detail (singular), as this is the correct key defined in the translation files. For example:

title: I18n.translate('jsonapi-resources.exceptions.parameter_not_allowed.detail',
                       default: "#{param} is not allowed.", param: param)

Solution

Update the code to use the correct translation key: parameter_not_allowed.detail (singular), ensuring it matches the key defined in the translation files.
