I am using Laravel 5.1 and for some reason I get this error from time to time:
UnexpectedValueException on line Response.php 397: The content of the Response must be a line or an object that implements __toString (), "boolean".
Which is very frustrating, it is very unpredictable, and it only happens from time to time, so it’s very difficult to even debug, as it is consistent. I have an easy way to simply upload a translation file, as shown below:
Route::get('test', function() { return trans('restaurant'); });
If I continue to refresh the page, it displays fine output in most cases. However, every 20-30 calls, I get an error! Can someone shed some light here, please?
Here is the stack trace:
