I came across an issue while doing Laravel 5, and that was the validation default
message key in the validation response array “The Given data was invalid”.
I wanted to have that set in a language file instead of using a static English string.
Here’s the file you need to edit at line 57.
parent::__construct('The given data was invalid.');
Set that to any language key you want, i chose ‘validation.message’ :
Have a good day.
