How to make Custom Rule with Eloquent work?

[dododaphne]

This is my request class:

class registerRequest extends FormRequest
{
    public function rules()
    {
        return [
            'email' =>[
                    'bail',
                    'required',
                     new EmailMustNotInUserDB
                ]
        ];
    }
}

This is my custom rule class:

class EmailMustNotInUserDB implements Rule
{
    public function passes($attribute, $value)
    {
        return User::where('email',$value)->count()==0;
    }

    public function message()
    {
        return trans('validation_custom.email_must_not_in_user_db');
    }
}

And I get an error:

local.ERROR: trim() expects parameter 1 to be string, object given {"exception":"[object] (ErrorException(code: 0): trim() expects parameter 1 to be string, object given at /var/www/core/vendor/laravel/framework/src/Illuminate/Validation/ValidationRuleParser.php:217)

If I comment out new EmailMustNotInUserDB in request class, the jsvalidation works, so how to make it work?(I'm using laravel 5.7)

Due to the volume of issues I'm afraid I'm closing this issue due to lack of activity. This avoids fellow collaborators wasting time investigating this issue, and also prevents giving a false impression that it will eventually be addressed.

To the reporter, please reopen if you still encounter this on the latest version providing a minimal test case. You can also contribute directly by submitting a PR.

Thanks.
